I don't know how they did it, but in Photoshop 6, it's actually possible to save an image as a 255-color gif file! I'm not kidding, either. Most of my sigs use colors that aren't on the web pallette... I think Photoshop selects the colors used in the image instead of basing it on the web pallette, which is one of the many reasons why it's so super duper cool
