What linux-based photo/image editing software for an experienced photoshop user
 

I am a fairly experienced photoshop user, but I enjoy linux more, Is there a photo editing software with features and interface similar to photoshop? Or should I just wine photoshop?

You may already have it installed. It's called gimp. There is a lot of on-line documentation (Grokking the Gimp) which is probably also installed. You can also google up a copy of Gimp Users Manual (2 parts, text and graphics. just unpack in the same folder). I had to take a Photoshop course in school, but I found that I could go home and do the same things with gimp. Some of the terminology is different, but the behavior is much the same. Like Photoshop, it's a resource hog when doing graphics manipulation.

Haha! :D I'll download it and try it.

you can even re-map some (most?) of the keystroke combinations in gimp similar to photoshop. takes a bit of time, but worth it if you don't want to memorize yet another set of key combo's
