Since Apple provides JPEG compression/decompression in QuickTime, not many
Mac programmers have bothered to implement JPEG on their own.  One
standalone Mac JPEG->GIF program is Jeff Lewis' "Imagery JPEG", which you
can get from the sumex-aim.stanford.edu archives (I think the file name is
/info-mac/app/imagery-jpeg-something).  Unfortunately this program is based
on an ancient version of the free IJG JPEG code, meaning it produces pretty
awful color GIFs.  But if you are on a black&white Mac, color output quality
may not be an issue... I believe there is a grayscale-only output option in
Imagery JPEG, and results in that mode should be OK.

You could also try Storm Technology's Picture Decompress, a free JPEG
viewer/converter available from sumex,
/info-mac/app/picture-decompress-201.hqx.  This doesn't need QuickTime, but
it does require 32-bit QuickDraw and gobs of memory, so it may not run on
your machine either.

The next release of GIFConverter will include the latest version of the IJG
code, making it capable of handling JPEGs with or without QuickTime.  That
will definitely be the way to go on old Macs once it's out.  I have no idea
how soon that will be...
