generating/resampling image data is a relatively heavy job for a script to perform. there maybe optimizations available in the script itself but generally caching the results the generation/resampling action is the way to increase performance ... you need a mechanism to check/store/ retrieve cached images [and a way to automatically regenerate a cached image when the sourceimage has changes].another thing to consider on top of caching is to store the cached data on a 'ram' drive ... on linux I often use a sub directory on /dev/shm (which is a part of the filesystem which actually exists only in shared memory - more than likely that you dont have access to this on a shared hosting environment.
Luckily I'm not in a shared hosting environment. :) I sit about 3 feet away from the server that is running my script. I will look into caching the info though to see if I can figure out what I would have to change/add/delete to accomplish this.
Would upgrading to PHP 5* be of any help? I've thought about upgrading but not knowing much about how to run the server from the command line(Part of what I'm learning) I didn't want to screw anything up.

I am moving along with a few additions and seem to be running into aproblem. The script I have works just fine, it's just slow when you putsome large files in it, the page takes awhile to load weither I'm calling it through the php file it's self or through a include in an html file.I don't know enough about php (read: Hardly anything) to figure out ifthere is an issue with the script that I'm using or if it's the hard ware that is the problem. The php script I'm using can be seen here: http://www.raoset.com/tests/picture/images/wheeler.php the html file I want to include it in is: http://www.raoset.com/tests/pictures/index.shtmlMy goal for this script, is to have it so that you can upload pictures into a specific directory, see the images display in a thumbnail format on the screen, and be able to delete the file if you did the wrong one.I know there are places like flickr that can do all of this, and it'sfree. But I'm in it much more so for the knowledge of learning how to doit.my php version is 4.4.1 and I'm running on a Power PC 1.2Ghz processor with 1.0 Gb of ram and 2 300gig HD stripped into a raid array to provideredundant backup. Anyway.. Let me know if there is any more info you need and thanks in advance for any help or pointers you could give!
