Brilliant! Thanks (John) for following through. I had the same questions
with the same responses you had to your answers. And I also don't have a

But does this all amount to an expectation that it will restrict the
upload to an image??
I've got this in my model:
class Photo(models.Model):
image = models.ImageField(upload_to='photos')

try:
p = Photo()
p.image = request.FILES['Filedata']
Perfect. Thanks. That's what I was chasing.

DJango's ImageFields uses the PIL verify to check the image.

No. The topic for django-developers is the development of Django itself.
Questions about the use of Django are off-topic and will be directed

I haven't read through the code, but the error must be caught
somewhere because I just tested it out.

My question is about the assumption...
As far as I can find, it actually only uses PIL to read the file and
return the dimensions. The code looks like if PIL thro

My understanding from what I've read is that most of the heavy lifting
for image handling is done by PIL (Python Im
