That fixed it! The only qt.conf file was in the site-packages/PyQt4
directory. When I copied it to the Python25 directory, the jpeg plugin
started working again.
I'm not sure why the PyQt installer didn't put the file there. I'm
don't have an admin login, but I do have write permission in that
directory. Or is it because Python isn't installed in its default
location (it's in C:/Source/Python25 instead of C:/Python25). The PyQt
installer does give a initial warning (incorrectly) that Python is not
installed, but the installer seesms to run OK otherwise.
