Yes. You use the GD library that PHP has (usually, sometimes you must
recompile it in).

Here's a resize script i wrote a long, long time ago. Its the first
half of the script:

basically, you open the file, use copyresized, then output it. Not too
difficult. In fact, I think the PHP manual might have an example in
it, possibly in the comments somewhere.
