There are several ways one might do this:
1) write a JPEG viewer in SF. This is the cleanest, best way. Do not do a
line-for-line port from C source. The result would most likely be big,
ugly, and fragile.
2) pay somebody else to do (1) above. If you have huge sums of money and a
long lead time, I might be convinced. A more reasonable approach might be
to pay Forth Inc. to do it so you won't have to deal with any of my nasty
personal habbits.
3) ask around. No, not here. I bet the firm Chuck Moore works for wrote a
JPEG viewer in Forth.
4) make calls on a graphics library DLL which speaks JPEG, like Davinci
                http://www.herdsoft.com/catalog/davinci.html
 or the Intel JPEG library, which might be a free downlad and may even be
redistributable, read the license:
    http://developer.intel.com/vtune/perflibst/ijl/

  Email me directly at kevin.appert_at_LMCO.com if you want me to look for a
public domain, free DLL

5) read a book. This always makes me feel better. You might decide to do 1
through 4 based on what you learn. Here is one you might try: (available
from Amazon, I bet, or http://www.pparadise.com/ )
