Hmm, OK. Unfortunately it seems that when a Mac user cut and pastes an 
image into an email, it uses TIFF - so the usual method of telling
someone to use another format doesn't really work.

The emails don't originate from Evolution and the images have a content
type of "image/tiff".

Basically, is this a generic issue that Evolution doesn't disply TIFFs
anymore, or is it specific to my system?
