I have noticed that different programs write GIF files in slightly different
manners (algorithms etc).

If you take a well written converter (say JPEG at 100% or GWS for IBM/PC) and
covert:

          GIF -=>  PCX   (or any other no-quality-loss format)

then

          PCX  -=> GIF   (effectivly ending up where you started)

the result is an identical PICTURE, but not an identical file- it may be shorter
(or longer) or  display faster/slower depending how good the program is.

I've got a PD JPEG for IBM- is it available for AMIGA?

If anybody REALLY needs Jpeg, I *could* e-mail a copy (trade?) of mine.
