The tutorial is geared for GIMP users, as that is what the author uses. The GIMP is the premiere image editing package for Linux. The GIMP is also available for Windows and Macintosh and other platforms. The GIMP has strong scripting features for the technically inclined. and best of all, it doesn't cost hundreds of dollars like some other proprietary applications.
For more information on the GIMP, check out their homepage, http://www.gimp.org/. They include all of the source code, and pre-built binary packages for a few operating systems.
If you use Adobe Photoshop, almost all of the steps described here have a clear and simple equivalent action. In some ways, Photoshop makes some tasks easier than in GIMP, but in other ways, GIMP wins in flexibility. It's just a matter of preference, for the most part.
