Without trying to plug myself ... I contributed to a book on the GIMP for
Linux. Prior tp being involved I though it was quite bare for features
.... dont let the simple interface fool you though its an extremely
powerful tool for doing almost any graphical manipulation including picture
touching (removing red eye etc) www.gimp.org has some great links to some
documentation regarding using the app as well as a few books that are out
there. The base for GIMP as far as my understanding, was actually
Photoshop so the interface might feel close to home.
