No, you can UPX images, you just can't UPX the stub itself.  For
example, the embedded CWSDPMI stub is 21Kb normally and around 13Kb
compressed with UPX (which you then have to modify yet again to 
get appropriate alignment) - but then even UPX doesn't recognize
it as a stubed image (since it doesn't see the stubinfo header
signature).  I only brought this up because someone really, really
wanted to save an extra 8Kbytes in their distribution by sending
a UPXed version of CWSDPMI.  The answer was no (and will be no for
the stub also) since it breaks stubedit'ing, breaks cwsparam'ing,
and breaks the copyright view just for saving 8Kbytes of disk 
space.

I don't believe what I refer to above will cause you any problem.
The CWSDPMI embedded stub is related to the PMODE stub, and you can
use it with UPXed images.
