Yes, the attachment can be opened and displayed nicely. But without opening it?
I am not referring to the MB or KB size of the attached picture, of course that can be reduced. I am referring to an attached picture that is of normal enough size (perhaps 160KB as this prints well on A4 and displays well without being pixelly and is not hard-drive storage hungry).
So if the attachment can be forced into a display that does not require the recipient to scroll up&down and sideways, that would be good. Apparently it can be done. I cannot discover how.
Obscurity is a comfortable cloak
