I'm not able to test this idea directly myself at the moment, but it
appears you're storing an absolute path (i.e., starting from the
filesystem root) in self.thumb. I'm pretty sure FileFields (and, by
extension, ImageFields) store relative paths from settings.MEDIA_ROOT.
(To make sure I'm thinking about this properly (since again, I can't
double-check this right now), you might want to see what the value of
the thumb field is in the database first. If I'm right, you should see
a path that consists of a relative path followed by an absolute one,
such as "2010/0104//home/username/webapps/media/2010/0104/
something.thumbnail.jpg".)
An absolute path is certainly helpful for actually operating on the
file, but before
self.thumb = imfile + ".thumbnail.jpg"
you'll need something like
imfile, ext = os.path.splitext(self.photo) # NOT .path, so this
is a relative path, not an absolute one
to make this work properly.
Hope that helps.
