Hooray for the burnallgifs meme!  Don, I take back everything bad I
ever said about the project.

There are three common ways to help produce small GIF files:

  1) Use the patented LZW compression algorithm (disabled by default
     in ImageMagick).  To enable this you would send Unisys a large
     check, and then enable LZW when compiling ImageMagick from
     sources.

  2) Reduce the number of colors in the image (e.g. '-colors 16').

  3) Don't dither the image when reducing the colors since this
     hinders compressoin.

or see if you can use another format instead.

If the handset has a fixed color map, you might look at using the -map
option to map the image colors to the colors directly supported by the
handset.
