Answer 1

Shouldn't replacing an image also remove the unneeded file from disk?

In the olden days, FileField was eager to clean up orphaned files. But that changed in Django 1.2:

In earlier Django versions, when a model instance containing a FileField was deleted, FileField took it upon itself to also delete the file from the backend storage. This opened the door to several potentially serious data-loss scenarios, including rolled-back transactions and fields on different models referencing the same file. In Django 1.2.5, FileField will never delete files from the backend storage.
