can't leave existing image in place if file field is required

[sheppard]

While a file field is required, the form requires a new file and does not allow leaving the existing one in place. Should perhaps allow fields like Django's form to leave or remove existing file separate from uploading a new one.
(edit: When the file field is optional, it's possible to submit the form without a new file; the existing file stays in place and there is no way to remove it.)

Not sure this happens enough to be a significant issue. Closing for now.
