GIMP is an acronym for GNU Image Manipulation Program. Now, I now what you're thinking..."huh?". I had the same reponse, and I'll admit I had to look up the meaning of GNU (a computer operating system comprised entirely of free software). Basically, this means that GIMP, despite it's rather unfortunate name, is a super-duper, Photoshop like, photo editing software that is completely free. That's right, free!
