mysql images: not caching

[amiller099]

I'm trying to figure out why my uploaded images are not being cached. This is not a local machine problem. I've tested it from many machines with different OSs & browsers.

I'm using php/mysql to store my images. When a <img src=blah.php?var=blah> is called, the image is re-downloaded every time. I'd like it to cache. Suggestions?

If you use a php script to generate an image the image doesn't exist until the script runs - therefore nothing cache. There is with gif or jpg's since they exist in a physical file which can be cached.

If this has not been resolved yet, have a look in the PHP manual under the function header I seem to remember it discusing HTTP caching using this function.
