The GIMP is almost exactly like photoshop, except without some of the tools and features in it's menus. (Not by many though, and the ever useful stamp tool is in it)
And I feel so sad when you refer to "The paint app available in computers".
It's as if other operating systems don't count as computers… Well, with windows as the basis of that, it's a good thing, I guess…
Sorry about my continued anti-windows rants, they're not meant to offend anyone living in WoW. (World of Windows)
P.S: Maybe I should try to photoshop-ify that up someday… Or someone else could, I might have trouble with the body art.
