I have seen a way to compress gif files.  I recently downloaded a program 
from a BBS call gif2jpg.  This converts gif files to the jpeg format.  On the
image I used, this gave me a savings of about 40%.  However, the jpeg format is
not directly viewable, the conversion is VERY time consuming, and the
conversion does not actually give you back the EXACT same image.  Some
degredation occurs, so I don't use it.  But if you want to compress some 
images for later viewing and you don't care about a little loss in quality,
you can use it.
