Between --size and --checksum, I suppose that's sufficient to validate
an image.

I think that if we can't talk to the server, or if the returned image
file is blatantly undersized (smaller than the smallest possible disk
image file) then we should log the problem (if we don't already) and the
image should show a "status" of "ERROR".

The fact that the image shows a status of "active" when it has a size of
zero is really misleading.
