2983	ImageField not deleing previously attached file when updated	Shimon	Tony Becker	"Steps to reproduce (in trunk):
1)Create a model with an ImageField.
2)Assign a new image to the ImageField.
3)Edit the object just created and upload another image to the ImageField.

Expected behavior:
Image file created in step 2 should be deleted (new file takes it's place).

In Practice the old image file is orphaned and never deleted.

I think this is serious because a malicious user can use any django image field to fill up the server hard disk (repeatedly change the contents of the image field) and fixing the situation without damaging a site is non-trivial as it requires the creation of a script that checks which image files are valid and which are orphans."	defect	closed	File uploads/storage	dev	major	wontfix	fs-rf-docs		Accepted	1	1	0	0	0	0
