Although Pan is full featured it has no manual and I cannot work out why it will neither display in some fashion downloaded images or simply launch them in image viewer without my first saving them, going to the saved directory and then launching it.

Simple to follow suggestion welcomed to make it work (like windows Agent to which it claims to be similar)
to either get rid of this

"Attachment not shown: MIME type image/jpeg; filename IMG_01852.JPG"

or better still to launch it in image viewer.
