IA has a lot of photographers and... er... amature photo editors and captioners, so I thought I'd get some advice. I'm tired of using MS Paint to resize images and winding up with grainy n00b crap. Are there any good free image editing programs I can download that you guys would recommend?

I use Picasa to upload pictures and manage them and do basic red eye and cropping, but I want something a little bit more capable. Thanks.
