Re: More efficient thumbnail script

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 source image 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.
