How can I copy a map into JPEG format to insert as a photo attachment?

quick and dirty: get the map on the screen as you like it. hit Alt+PrintScreen now to put the screen shot in your clipboard make sure your graphics program is open
Ctrl C or paste in the screen shot.
now fix with graphics program as needed. :D

I highlighed a method to do it in an article some time ago..
