About storing images on a server... I did that for awhile, but once i hit
1000+ images, my scripts started timing out.(from reading the directory)

Hi Jen, here's some code I posted up in the general ng for storing in db and
retrieving images from db for display on your page.
It's recommended that you stay away from storing actual images in the db. If
you are storing a path the code below might help you out. It select a
firstname, and
an image according to an id. You'll have to change the youridentityfield
and youridentity values to suit your needs.
# display image from db
#
#connect to db
$connectionToDBid = odbc_connect(ceo34deesnr43ipits, joeyscode,
joeyscode);
// sql statement
$sqlb = SELECT imagepath, firstname FROM IMAGES WHERE youridentityfield =
. $youridentity;
# execute the query
$resultset = odbc_do($connectionToDBid, $sqlb);
$image = odbc_result($resultset,1);
$firstname = odbc_result($resultset,2);
print brbrbrdiv align='center';
print table width='400' border=0 cellpadding=2 ;
print trtd align='left' ;
print font color='#ff' face='verdana'h4 . Welcome back .
$firstname . /h4/font;
print /td/tr;
print trtd align='center' ;
print img src=' . $image.' align='center' border='0'br;
print /td/tr;
print /table;
# close the db connection here
# end of display image from db
#
#photo upload form
Here's a common form that allows you to upload a file (say an image) to the
db
form action='upload.php' method='post' enctype='multipart/form-data'
input type='hidden' name='MAX_FILE_SIZE' value='102400'
Pfont color='#ff' face='verdana' size=1Upload Photo:/fontinput
type='file' name='userfile'input type='submit'
value='Upload!!!'/form/p
end of photo upload form
##
start of upload process to db
?php
# $userfile is the file being uploaded
# print $userfile . BR;
# print $userfile_name . BR;
#use a time stamp plus the original file name to uniquely name the image
before storing in db to prevent two files with the same name
$timestamp = time();
$userfile_name = $timestamp.$userfile_name ;
// copy the file being posted -- remember to escape backslashes!!!
if(copy($userfile, /ez/codesnipits/consultant/tempimages/.
$userfile_name)){
print font face='Verdana, Arial, Helvetica, sans-serif' color='#663399'
size='2'Your picture has been uploaded successfully and has been made
available for
online users to view./fontbrbrbr ;
}
else
{
print font face='Verdana, Arial, Helvetica, sans-serif'
color='#663399'Error encountered during resume upload process./fontbr;
}
$patharola = tempimages/. $userfile_name;
// insert path into database here
# connect to db
$connectionToDBid = odbc_connect(cdefc5onwesulertt, joeyscon,
joeyscon);
session_register(consultantid);
$consultantid = $consultantid;
# create query statement -- update image field in db using path
$sqlr = UPDATE CONSULTANT SET image= '$patharola' WHERE consultantid= .
$consultantid;
# execute the sql statement (query) on the connection made
$resultset = odbc_do($connectionToDBid, $sqlr);
?
end of image to db process
##
Hope this helps you out :)
Cheers Joe :)

Re: [PHP-DB] Re: A good tutorial
Hi again JD...I got to thinkin':)
Just out of curiosity...how many images were you bringing back from the db
when your script timed out?
I store the path of my image in the db and echo it out when I need to.
Cheers Joe:)

RE: [PHP-DB] Re: A good tutorial
It has never timed out bringing back from the db... only when reading from
disk.
I think the big difference is I need to create both fancy web pages and neat
printable pages. So I need to open up an image stream to manipulate the
photo.
I had a top level dir called photos, then a sub folder named from the row id
in the MySQL table.. so the path was always something like
/photos/1066/photo.jpg
once I hit 1000+ records (thusly, 1000+ sub dirs in photos/) ... it would
time out opening the 1066 directory. (displaying 15 records at a time) It is
much faster now with a separate table with binary data and storing just the
id for an image in the original table... then just select using an id. ( a
separate select staement seems to be faster than joining the tables) The
biggest problem tho was that I have two servers working as web farms. if one
domain needed access to the photos from another domain located on the other
server, I could not open the photos. (For resizing and such) When they are
in the db, I can get them from anywhere.
