I'd have to put in a word for Cloanto's PPaint in terms of Floyd-Steinberg dithering. Often you can do a great anti-aliased image in TVPaint (free for download from our site, btw -

and then dither it down to a 64 color GIF in PPaint very easily. For whatever reason, while PPaint can read JPEGs no problem, I've never seen where it can actually *save* in JPEG format. . .
