Don't you have to have a license to be able to produce the GIF files?
I'm currently working on a map project which invokes heavy imaging, and
GIF was rejected for that reason (I remember VERY high figures, like
flat $80K/year for using it).

TIFF is good, as I remember, but its advantage of being flexible is also
a disadvantage at the same time - it's too damn difficult to implement,
unless you implement a limited subset. But, also, it supports tiling,
which may be useful from a MUD standpoint.
