According to this only 256 colors can be used per image block although
the amount of colors in the whole image can be larger.  But the page also
says that most (image creation) programs don't support more colors for
gifs and that it's impractical to use them.

So I don't think they're common on the www-pages and a browser, especially
for something like Atari machines where performance and memory usage is
more important, could treat & store them as 8-bit...
