ImageField.clean does some validation that the given file is, in fact, an image, but then just returns whatever the FileField gave it-- generally an UploadedFile.
I have a later Form.clean_* method which needs to do further work with the image, and so uses Image.open again.
I think it'd be good to annotate the UploadedFile with an image attribute to save the work of parsing the image yet again.
f.image = trial_image
