Try Neuquant - a simple Kohonen NN based method.

there you will find sources (ANSI C, yuck), the paper itself is not available on the
Web, but the source is pretty straightforward and easy to rewrite in a simpler
manner. A bit slow, but perfectly passable for offline use. Produces much, much
better results than the other two methods I tried - Heckbert quantization and
a simple elimination of the closest colors.
