Is there some way to speed up a webpage, which uses the same images each time. I think this could be done be caching the images, but I can't seem to find any documetation of caching data in php?
Do you generate the images 'on the fly'?
A forum, a FAQ, what else do you need?
No! images are .gif or .jpeg
Then it's up to your clients to cache them or not, and there is very little you can do about it. (clients can override every cache parameter you send along)
Most browsers are configured to cache images by default.
