I like gimp... **** GIMPS! LOL
Do you even know of any other big-time graphics programs for Linux? I sure don't. But I don't really see any reason to look around for a different one, the GIMP rules.
I know a for, many of them were just ported over. Corel tried to pull some **** off. Yet amen to that, hail gimp LOL. Now I need to puke because I had an OD of "energy" drinks... Ohhh my head... blahhhh... feel free to post why, what prog, and lil tips bout em thanx (/me leans over and pukes in bucket).
the gimp is THE linux graphics program. I guess with open source you dont need competition since everyone can contribute to the same program. There are others though, simple "paint" programs.
Moonlight - is a 3D graphics program. In my opinion its kinda difficult to use.
