Currently the resize method of DjangoProvider raises an exception if the
image field is not a ImageFieldFile. However this requirement is used only
to get images heigth and width, and in the same function is already the
code to get those fields with PIL.
With this patch any FileField-like field could be used;
sorl.thumbnail.fields.ImageField for example. (I pasted the patch directly
since didn't find a way to attach files).
