The truth is, not all images are born equal :p
There is *no way* to take a full color photo and convert it to 16 colors 
and have it still looking good. OTOH, a drawing will convert much better 
as it already uses very few colors.
The best thing is to plan ahead and have in mind from the beginning what 
you need, make use of as little as possible colors and gradients. Maybe 
have two variants of the image: on with few colors and another one 
without limitation and use each image where is appropriate.

GIMP have 4 options for dithering and for each image another one may 
produce the best result, so you really have to experiment.

Use this as a starting point: http://gug.sunsite.dk/tutorials/tomcat15/ 
, it is about reducing to 256 colors, but it may be useful.
