Hi There,

 I just did some quick tests on this. It seems that the conflict comes from
the
gd library built in jpeg and the one used with mapserver.

 To test it, I have recompiled mapserver with gd where I removed the jpeg
support (USE_JPEG flag) and I could load the jpeg files.
 The real solution for me is to recompile gd with the same jpeg lib that is
used
for mapserver. Unfortunaltly I could not do this right now, It does not
compile
on windows out of the box (I am currently using precompiled binaries). I
will
try to do this some time this week ....

PS : I have entered a bug relative to this :
http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=203
