Has anyone use GIMP (macgimp.org) or FILM GIMP http://filmgimp.sourceforge.net) both are open source photo editing software..so its basically FREE Photoshop. Well, I dont really understand how to install it... "Free at http://filmgimp.sourceforge.net, available as source tarball (gz), download version 0.10 or higher (about 3mb). Requires Fink (free, see http://fink.sourceforge.net/)." That, reading from Fink website, Fink also install software like xfree86 and OroborusOSX into your computer? so whats xfree86, x windows, and oroborus OS x?
