Fails to extract downloaded remote images from message preview
It is common these days to receive emails containing embedded images which are remote links. Facebook users, for example, do it all the time (FB tracks user connections through fingerprinted image filenames, etc). But also legitimate corporate email without privacy concerns. Currently one can "load remote content" in Evolution email window, but one cannot either copy the image to the clipboard after it has been loaded, nor save the image locally, which is another very common thing to want to do. Also, if this email is forwarded to others it will not contain the image (but I think it contains the link, thus furthering FB's and other trackers purpose).
It would be nice to be able to copy/save the image once loaded. An additional benefit might be obtained if when forwarding such an email, the link is eliminated and an actual embedded image used instead.
