GIFs are evil. From http://www.libpng.org/pub/png/ :
``PNG was designed to be the successor to the once-popular GIF format, which
became decidedly less popular right around New Year's Day 1995 when Unisys and
CompuServe suddenly announced that programs implementing GIF would require
royalties, because of Unisys' patent on the LZW compression method used in GIF.''
Note that this is only for writing GIFs, not reading. Basically you need
to pay Unisys 5000 US$ (IIRC) if you want to make gif files.
Remember the ``burn all gifs day''. :-)
