I use an iMac desktop, settings are all default, I only use it for email and occasional surfing or YouTube poking about. Mostly I do email, and when I send along a photo I drag it from the desktop. My problem is I've one correspondent who sends messages, sometimes with a photo. The message is just that, but if there's a photo, thwart is always a duplicate photo as well. She'll send a link and photo, I always get two photos in same message. She says it is me, it doesn't happen with anybody else she sends things to. That I know of, she is on a Mac laptop, but uses a different mail program and browser, sometimes dragging a desktop photo into her message, sometimes using the "paperclip." From nobody else do I get duplicates. Can anyone figure this out for me?
