Kat,
if you use an AMIGA machine one of the best programs to use
is Zgif, or – to be able to change them – ImageFx. The latter was
given away on the UK magazine CU Amiga june 95 on two floppies.
Imagefx lets you import any gif /iff/ jpeg/ bmp/ or whatever fileformat and
change it.
If you want more assistance please mail me,
