So you are able to view GIF files that you can view in a PC/Unix/Amiga
(eg. from wuarchive)(biggests gif site I've ever found) in IIGIF? 
When I tried doing that, I get garbage.  But when I view GIF files 
I grab from Apple sites, it works. In fact, I remember now. There was
a program I had to use (STRIPGIF, you can download it from the msdos/gif
directory in Simtel20 or Wuarchive) to strip the extra header off of
Apple gif files before you can view it on a PC/Unix. It worked too but
since it was such a hassle, I just ended up having two sets of gif
files. Maybe that was the Mac gif format, but I had to use this "Apple"
gif format before IIGIF can read it. PC gif files displays garbage.
Is there a new version of IIGIF out that can accept non "apple" gif
files nowadays? Grab a gif file from wuarchive.wustl.edu in the
directory graphics/gif. It has so many files that they're separated
by the first letter of their filename in separate directories. So
directory a/ contains files starting with 'a' and b/ with 'b'....etc.
Just grab any file and see if you can view it under IIGIF. Or if you
already have a gif from a PC hanging around somewhere, see if you can
view it under IIGIF. Maybe I don't have the latest version.
