#10935 closed Cleanup/optimization (fixed)

forms.ImageField.clean should annotate the object returned by FileField.clean

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 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

Also, as long as it's opening the image, I think it should correct content_type based on the actual format of the image. Most OS's will mis-report the content type of the upload based on its extension, so that a JPEG named something.gif is reported as image/gif.
