Catch all upload exceptions
Catch all upload exceptions

Uploading can return a wide range of exceptions, all of which should
be logged into the individual upload logs.  Thus catch all exceptions
and log them before passing on.

While we are here, add a bit more helpful verbosity to the status logs
by logging the image_name and id everywhere.
