Where can you get GIMP?
There are several builds of GIMP. each available for different operating systems. The ones on the main GIMP website are actually source code and binaries for Linux. There is a separate site for the Windows build, at least two different builds for Mac OS X, and the modified version known as GIMPShop, which is designed to resemble Photoshop. Links to each of these can be found in the "Related links" section below.
