[PHP] Re: Image Type BMP @ Save Image As Dialog on IE
Nitsan Bin-Nun napsal(a): I have wrote a PHP script that serves JPEG images in smaller size, the resize is done using GD on-the-fly. I have noticed an interesting issue during the save image as... dialog on serveral internet explorer browsers, somehow, for some strange reason, the JPEG file is shown as BMP file. I don't know why this is happening, but I'm trying to make it save it as JPG file. In firefox or any other browser everything works like a charm. I have to mention that the JPG file is located in the HTML in the following format: img src='xxx.jpg' alt='aaa' style='border:0;' / I have also used mod_rewrite to serve the file with .jpg extension (I thought that the strange IE may not know how to recognize it..), the PHP file is sending the correct headers, I'm attaching an example for HTTP request response for this resized image: GET /gallery-image-dolphinim-12450163853.

[PHP] Re: Image Creation
Ahh now it becomes clear, you where trying to place the image inline.
There is a way with base64 encoding, but it isnt supported by many
browsers - you can actually say IMG SRC=data:image/png,base64;[...];
where the [...] is the base64 encoded image, so you would need to wrap
an ob start and ob end around your code to catch output, then base64
encode it then display it.
The problem is it dosnt work in IE because IE dosn't support this. Its
also not very nice for anyone not wanting to view images as they will
have downloaded the image even though they dont want to see it. There
was a very good reason why I know that and have done it, but more then
99.9% of the time, its not the way to go.
(the case in example was an embedded application on a machine that had a
pseudo-web interface but no webserver - it would wait for a connection
on a port then dump a stream of text which would be in HTML - there
was no webserver there it would ignore any http headers sent).

Dude - that works fine!
can you check your code - make sure you havnt got any white space at all
before the php starts in ANY file, and then check that you've got ALL
erros being reported (because you might have the error cant send headers,
output allready sent at line x) which will prenvent the header being sent
and then you dump the image to the screen which is the random wierd
characters (that means the image create functions are all ok and
installed, and you have an image object or similar).
my code was simple ?php {your function} makepie(10,100); ? NO WHITESPACE
NO BLANK LINES NOTHING.
(ps you might even have a php include in the php file (php prepend or
something?) which might be inserting a space or a newline or ending
headers or something. Look at error_reporting() or similar in the manual
to turn error reporting on for your script.
Hope you find the bug, thats quite a nice function you have there.

I think I fixed my own problem. I tried calling the PHP script from a

It was about where to store images uploaded by website users and
question was database vs filesystem and dedicated vs shared hosting
and the conclusion I could understand was
fast,secure,cheap pick any two
1) database + shared = secure and cheap
2) filesystem + shared = fast and cheap
3) filesystem + dedicated = fast and secure
4) database + dedicated = err.. stupid? ;)
For now I have decided to try option 1 and see how far I can go till
performance begins to become a limiting factor and then decide later if
I really need to, to choose between security and cost.
I have another question. I have used mysql mediumblob to store images.
They are jpeg files. When I retrieve that binary data with a query and
generate an image with PHP .. ie. I do
?
...
header('Content-type: image/jpeg');
echo $binary_data;
?
The image gets generated and displayed OK. But when I save that image
file on my work station it gets saved as a huge file .. a file which
was 36 Kb jpg when uploaded is saved as 5Mb bmp when downloaded. The
data in mysql column is 36 Kb only. So why is it getting saved as such
a huge file and why bmp when header is 'image/jpeg'

Before I used 'if... else' but it wasn't working so I
made a test with a second 'if'.
I print the result of the variable to be sure that the
number is really different, but anyway the picture is
always the same.

Bob Eldred wrote: I'm wanting to serve images outside the docroot of apache, so that the images can't be so easily hijacked. However, I appear to be running into a problem with (I think) the headers not being sent properly. IE (v6) will only save the images as BMPs, not as JPGs, even though they are JPG images. Given that your purpose is for the images to be difficult to hijack, doesn't this serve your interest? :) The problem with IE is that it's developed by Microsoft. The same way Microsoft didn't recognize magic for detecting the file type (and used extensions instead), it now doesn't use MIME types (and uses extensions instead). Never tried it, but I would assume that serving an image along with the proper headers and with a .txt extension to IE will result in saving it as text. So basically it's an IE thing. What you can do, if you really need to, is serve the images as img src=/showpicture/xx.jpg and parse the xx out of it in showpicture.php.

RE: [PHP] Re: Image resolution and php
Images don't have a resolution per se; display devices have a resolution. Images (the formats you're talking about, anyway) are measured in pixel width and height. The height and width in any units other than pixels of course necessitates conversion - for an easy example, a 300x300 image on a 1200x1200dpi printer will be exactly one quarter the size of the same image printed on a 300x300 dpi printer. -Original Message- From: Jome [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 18, 2002 8:11 AM To: [EMAIL PROTECTED] Subject: [PHP] Re: Image resolution and php I need to get resolution information (dpi) from any image of jpg, gif or png formats.

Re: [PHP] Re: Image resolution and php
I believe that image files on the Mac platform contain metadata that does in fact include this information. Sherlock on Mac OS 9 is not capable of finding this information. However, I did find the following information for Adobe Photoshop 7 for Mac OS X on how you can achieve this. I don't know if Adobe Photoshop 7 for Windows can do this. From: http://www.apple.com/macosx/applications/photoshop/ You have thousands of digital pictures and graphics stored on your hard disk. Wouldn¹t it be cool to be able to verify what¹s in an image file before you click on it? Adobe thought so too, which is why the new File Browser in Photoshop 7.0 lets you do just that. The File Browser lets you view your thumbnails and image metadata like color profile, date modified, and the Exchangeable Image File (EXIF) information generated by digital cameras to make sure the images are what you¹re looking for before you open them. As an added convenience, Photoshop lets you add ranking to your file criteria. You can have your own ranking system for identifying images with, for example, rankings such as ³Proof² and ³Final.² You can also sort images by file name, file width and height, file size, file type, resolution, color profile, date created, date modified and copyright. The File Browser also gives you the added advantage of being able to search for images visually rather than just by file name. Eric C. Pollitt, Founder 401 E.

[PHP] Re: Image library
Lots of good ideas. One other thing to consider when designing this is the possibility of multiple web server accessing a single database server. If you use the file system method which assumes that the web/db are on the same server as soon as you want to have multiple web servers you'll run into problems. Of course you also probably don't want to have multiple web servers ask a single db server over and over for the same image. Especially if mysql's blobs are inefficient (I don't know if they are or not). You might consider storing the images in the database, and then setting it up so that it first checks the filesystem and if it isn't there, gets it from the database and caches it to the filesystem so the next access it fast. This would allow you to run multiple web servers since they could both cache them locally. For what it's worth, for our application we use a two level directory heirarchy of [0-9]/[0-9]/primary_id.jpg. Works well for us. -philip On Wed, 21 Aug 2002, Scott Houseman wrote: Hi there.

[PHP] RE: Image library
[snip] Having a large number of files in a single directory does affect performance, the degree of which depends on the filesystem. This is generally accepted wisdom for dealing with large numbers of files - but what number is considered large? Any rules of thumb, for different OpSys/file systems? [/snip] I guess the situation I have had (various OS's) and numbers of items in the file(s) (upwards of 40k items) I have never encountered a degredation in performance that could be deemed noticeable. I could perform some file retrieval analysis to see time lags, and I am sure that there would be some dependent upon the file system (and OS), not to mention hardware factors, the most significant which comes to mind is hard-drive seek times. But as yet, none noticed... You could probably find info on this if you dug around in the linux/freebsd source code... I think more important than how many files can you fit in one directory before things start to suck is the issue of that directory getting big enough (kilobyte wise) that it fills up the partition. If you put them in separate directories to start out with you can always add a new disk (fileserver, etc.) and put half of the directories on the new disk, mounted in the same place.

Hi again, I guess one really good reason for not storing images directly in a db table is performance. When you store a blob in a table it affects the whole database's performance. It slows it down, that's why the most common method is to store the images in a dir on the webserver and store only the path to the image in the databse field. That code I posted in the previous will allow uploading of an image to a directory on the server, store the path to the image in the correct record for retrieval at a later point. It also retrieves an image for a particular record. HTH Joe :) Zara E Gonzalez [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Joe (And/Or others),
We are storing the actual images in the DB. We did not want our pictures to be
on our webserver. Instead we felt it would be better to keep them on the
database server. In order to do this, they had to be stored in the database
itself since the database server is not accesible by the web. (I.e. the only way
to get stuff off of it via the web is to pull it out through the DB connection)
Now, You say that it is not recommended that we store our images in our

Re: [PHP] Re: Image Fields and PHP...
It basically comes down to speed. While there is nothing Technicaly wrong
with storing the images in the database, accessing the images will become
slower as the database gets larger, than if the files were stored on the
filesystem. Whether or not this degredation of performance is acceptable or
not is up to you, but... if you still want to pull an image directly from
the database, try the following method. Please note that you must have the
image type stored in the database as well.
Create a seperate PHP script called getimg.php:
/* Begin getpic.php */
?php
if($id) {
$dbhost = ; /* MySQL Server */
$dbuser = ; /* MySQL UserName */
$dbpass = ; /* MySQL Password */
$dbname = ; /* MySQL Database */
$db = mysql_connect($dbhost, $dbuser, $dbpass);
mysql_select_db($dbname,$db);
$query = select image,type from images where id=$id;
$result = mysql_query($query);
$data = mysql_result($result,0,image);
$type = mysql_result($result,0,type);
Header( Content-type: $type);
echo $data;
};
?
/* End getpic.php
Now that you have this, when you want to display a picture, call getpic.php
in your img tag like so:
IMG SRC=getpic.php?id=12 (obviously, this gets the picture with ID 12
from the database. )
There are probably more elegant ways of doing this, but it works. :)

Joe (And/Or others),
We are storing the actual images in the DB. We did not want our pictures
to be
on our webserver. Instead we felt it would be better to keep them on the
database server. In order to do this, they had to be stored in the
database
itself since the database server is not accesible by the web. (I.e. the
only way
to get stuff off of it via the web is to pull it out through the DB
connection)
Now, You say that it is not recommended that we store our images in our
database, can you give me a reasons why?
Thanks,
Zara

RE: [PHP] Re: Image Fields and PHP...
Actually, I can't do that. Which is the whole problem I'm having. PHP fails when
I try to pull the image field out of my database. After talking to others I
thought it might be the @@textsize variable in MSSQL unfortunately setting it to
a lower value did not solve my problem. I have recently spoken to another person
who is having the same problem as I am and it appears to be a problem with one
or all of the programs I am using. (MSSQL, PHP, and FreeTDS)
I guess I'll have to change how my system is set up after all.

It basically comes down to speed. While there is nothing Technicaly wrong with
storing the images in the database, accessing the images will become slower as
the database gets larger, than if the files were stored on the filesystem.
Whether or not this degredation of performance is acceptable or not is up to
you, but... if you still want to pull an image directly from the database, try
the following method. Please note that you must have the image type stored in
the database as well.
Create a seperate PHP script called getimg.php:
/* Begin getpic.php */
?php
if($id) {
$dbhost = ; /* MySQL Server */
$dbuser = ; /* MySQL UserName */
$dbpass = ; /* MySQL Password */
$dbname = ; /* MySQL Database */
$db = mysql_connect($dbhost, $dbuser, $dbpass);
mysql_select_db($dbname,$db);
$query = select image,type from images where id=$id;
$result = mysql_query($query);
$data = mysql_result($result,0,image);
$type = mysql_result($result,0,type);
Header( Content-type: $type);
echo $data;
};
?
/* End getpic.php
Now that you have this, when you want to display a picture, call getpic.php in
your img tag like so:
IMG SRC=getpic.php?id=12 (obviously, this gets the picture with ID 12
from the database. )

[PHP] Re: Image generation scripts
Terry, Their is a cool class someone has made to make it a snatch to add graphs charts, and so forth. Make a search for google for PHP graph its the first result JPGraph. I highly recommend it for your project. Regards, Yoep Step One [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Hi there! I'm writing some stuff for a non-profit site as voluntary help. Does somebody have any PHP image generation scripts (GD) that could be used to pretty up a statistics page. The produced image should be a chart, pie, bars or something similar that could visually represent various statistical information. It would be great if one could specify background images etc. The image should be a bit more beautiful from the pie chart at http://skydiving-org.freeservers.com/stats.htm A bit more customization and visual attraction would be great.

[PHP] Re: Image problem
I've instaled and cofigured php4 on WinNT with Apache Web server. I can't use any fuction of Image manipulation, 'cause I get this error message: ImageGif: No GIF support in this PHP build In phpinfo() is listed that: gd lib. enabled, zlib lib. enabled. What do I still miss there? In the newest version of GD library (think it since about 1.3 or something) does support GIF, because GIF is a commerial image format. Use PNG or JPEG instead. That much better, or find a version with GIF support. You can see what Image formats you GD can use by make a file with follow content: ?php phpinfo(); ? :o) Regards, Johan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

RE: [PHP] Re: Image problem
PHP needs to be compiled with libjpeg and libpng in addition to the GD library to use those formats respectively. The PHP manual section covering image functions (including those for manipulating JPEGs and PNGs) is at http://www.php.net/manual/en/ref.image.php -Andy -Original Message- From: Peter Lalka [mailto:[EMAIL PROTECTED]] Sent: Friday, December 07, 2001 5:50 AM To: [EMAIL PROTECTED] Subject: Re: [PHP] Re: Image problem Thanks, in phpinfo list really isn't support for GIF:( How can I manipulate jpeg images?
