Rated 5 out of 5 stars

It is a very handy thing to send multiple photos as attachments. I used to have a different one for earlier versions of T-Bird, but it was discontinued.At the moment we use this on two Win XP computers and we both have the problem that it places all the sent items in LocalSettings/Temp making it huge (I mean Gigs of rubbish) after a while. It would make the add-on much more desirable and better if it cleaned up after itself.

This review is for a previous version of the add-on (2.8.1-signed). 

I'll look into doing something about that. You must send a LOT of photos for that to be an issue though!
