I used to use gimp, but photoshop does everything nicer. Though I suck with it. I might just install gimp again. At least I know my way around with it. I learned that program by just trying stuff. At least its interface makes sense unlike the one in photoshop cs3. I had to search the web and ask everyone to do the simplest of things (rotating a selection, deselecting, how to erase to transparency, etc).
If I could 'obtain' a version of photoshop, I would learn to use that, but I cant seem to find it. Until then, ill continue using GIMP and Macromedia Fireworks 8.
