As far as I know, PyQt has no options for enabling or
disabling jpeg support - the jpeg handling appears to
be done at the C++ level, so if Qt has jpeg enabled,
that should be sufficient.
I also tested your program on a different machine
running Qt 3.03 - works fine there also. I have no
idea why you're having problems. Some of the things
you might try are full explicit paths to the jpg files,
different jpg files, make sure the jpg files you're
referencing are actually readable. Do you have
multiple versions of Qt running? If so, be sure that
Qt 3.0.5 libs are being found by PyQt at run time.
Run ldconfig just to be sure. Do the PyQt example
programs (in PyQt-3.3.2/examples3) work? Delete any
older PyQt files and re-run 'make install'.
Sorry I can't be of more help.
