@xes working on it. Just asking for peterleinchen's opinion before I do it. Also thanks for approving everything.

As for the request, if it manages to insert the picture into the db then it should be possible to view it.

Since the error "impossible to download" isn't hardcoded, I can't track down where it's failing.
If you have the log file or the error from stdout showing how far it got, that would be helpful.
Though you may need to remove any personal info before posting it.

I did try to reproduce it but fMMS sets the subject/description as 'MMS' if it's blank.
