You may be able to use http://php.net/dl to load the extension (you'll need to build it to be compatible with your host and then upload it) but it's highly unlikely they'll have the dl function enabled. Your best bet is to ask them to add it to their environment. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/ On 4/29/2011 9:26 AM, Stuart Dallas wrote: On Friday, 29 April 2011 at 03:33, Mitch wrote: I have written a lightweight, easy to use photo album system in HTML/PHP/MySQL.In addition to the Photo Album side I have written a series of Admin Utilities to manage it with.

Re: [PHP] gd Graphics Library Question (EXIF)
Hi Mitch, you could try with http://www.php.net/manual/en/function.exif-read-data.php I did a test with image jpg and this was the result: FILE . FileName: bruce_lee_black_white.jpgbr/ FILE . FileDateTime: 1304086298br/ FILE . FileSize: 33464br/ FILE . FileType: 2br/ FILE . MimeType: image/jpegbr/ FILE . SectionsFound: COMMENTbr/ COMPUTED . html: width=353 height=450br/ COMPUTED . Height: 450br/ COMPUTED . Width: 353br/ COMPUTED . IsColor: 1br/ COMMENT . 0: LEAD Technologies Inc. V1.01br/ Anyway taking account *EXIF headers tend to be present in JPEG/TIFF images generated by digital cameras, but unfortunately each digital camera maker has a different idea of how to actually tag their images, so you can't always rely on a specific Exif header being present. * Regards.

[PHP] GD Graphics Library
There are several functions in the GD library that I really, really want to be able to use on several sites that I develop/manage. Unfortunately, the ISP I use, FatCow, doesn't have GD, nor seems interested in adding it. Can anyone recommend a good, cheap ISP (like FatCow) that DOES have GD for PHP4? (Or better yet, do you have any suggestions as to how I might persuade FatCow to add it?? ...Rene --- René Fournier, [EMAIL PROTECTED] Toll-free +1.888.886.2754 Tel +1.403.291.3601 Fax +1.403.250.5228 www.smartslitters.com SmartSlitters International #33, 1339 - 40th Ave NE Calgary AB T2E 8N6 Canada -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
