I had a problem: height_field and width_field always = 0 in some models, after uploading any image file.
Problem was in fields order: if height_field and width_field goes before image field - this thing happends.
I appears in models save method.
/django/db/models/base.py : 378 (actual for revision: 9962)
values = [(f, None, f.get_db_prep_save(raw and getattr(self, f.attname) or f.pre_save(self, False))) for f in non_pks]
here all fields values are calculated (get_db_prep_save) and copy to values. So, if in models description ImageField goes before height and width fields, everything is fine. But if ImageField goes after this fields, all pic size calculation still in fields but not in values list.
