I guess that could work if mail clients don't have timeouts for images.

I still can't imagine how they would detect deletion though.

They're just calling "viewed for <x seconds" a deletion, it seems...

A timeout would possibly be after an engagement time that means "probably read the whole thing", e.g. 60 seconds.
