Certainly nothing beats it for quality. I've found the Python Imaging
Library faster for resizing images--though of course PIL is a
programming API rather than a command line app.

Not exactly. The patent is on the compression algorithm normally used
with GIFs, so if you create uncompressed GIFs you should be in the
clear. Also, I recently heard someone say that (Compuserve?|Unisys?) has
decided to stop hounding people about GIFs, because they were getting
too much bad press about it.

Nonetheless, I agree that PNGs are preferable, both on principle and
because they seem to preserve the image quality better.
