Many eons ago I created a set of icons from Dawn of the Dead images. I did it for the hell of it, and actually still populate my Win XP driven computer with a few of them. As I am about as illiterate when it comes to MACs as my father is to any technology in advance of the wheel, I couldn't tell you if these will work with a MAC system. If from what I gather is true about the nature of PCs and MACs, then I doubt these will work. In fact, given that PCs and MACs were created within an aggressively competitive economic system, I'll bet my bottom, capitalistic dollar that these won't work on a MAC system. Sorry MAC users! As for the rest of you... enjoy!
