Thanks, but that wasn't the problem. I had caused it with hacking detritus.

But I notice an interesting difference in the name and place of the dll. Yours
is right under site-packages\ as PIL_imaging.pyd and mine is under
site-packages\PIL\ as _imaging.pyd. Did you install via the binary installer?

BTW, if the effbot is lurking, I would offer a patch to Image.py which would
