[quote:18cbb4cef8="redshine"]The Gimp is a program you can download free from the internet. If you want more features and for it to work with photoshop plug ins you have to buy the proper version.[/quote:18cbb4cef8]
What "proper" version? I thought it was totally free software?
Anyway, the name is stupid, but stands for [b:18cbb4cef8]G[/b:18cbb4cef8]NU [b:18cbb4cef8]I[/b:18cbb4cef8]mage [b:18cbb4cef8]M[/b:18cbb4cef8]anipulation [b:18cbb4cef8]P[/b:18cbb4cef8]rogram. (GNU stands for [b:18cbb4cef8]G[/b:18cbb4cef8]NU's [b:18cbb4cef8]N[/b:18cbb4cef8]ot [b:18cbb4cef8]U[/b:18cbb4cef8]nix.)
As for manuals...
Online docs: http://docs.gimp.org/en/index.html
PDF downloads: ftp://ftp.gimp.org/pub/gimp/docs/
"Grokking The GIMP" (book): http://gimp-savvy.com/BOOK/index.html
There's also a version of GIMP called [b:18cbb4cef8]GIMPshop[/b:18cbb4cef8] for people who're already used to Photoshop and don't want to learn new menus and stuff. It's just a different look, though - not a different feature set. Not sure if this is the homepage, but there's an announcement with downloads: http://plasticbugs.com/?page_id=294
