Hi, I haven't much forms with image/files, but I believe you should do
something like this:
photo = self.cleaned_data.get('photo')
This is for your second version.
When doing stuff like this I find it sometimes can be helpful to
insert an error like just typing raise. Django will in the debug
screen let you look at your variables. So you could see what you fx
are getting when you do your photo = ... and see why it raised that
error.
Hope it helps
