  Well, my advice would be for you to get a hold of a set of utilities
called PBM plus.  The PPM (Portable PixMap) format is able to write to
Color PS, and it will read from GIF and many other formats.  I don't
know where the best place to get this program is, but it's wonderful,
and it should be pretty easy to find.  Best of luck...
