I don't think there's a notification sent to the person who uploaded a pic if someone starts a discussion about it. Is this correct? If so, would this be difficult to add? I hate to think I might have failed to see and answer a question anyone might have had about a pic of mine in the past, and don't always frequent the forum where those discussions appear often enough to ensure that I don't in the future. TY!

You will get notified. If someone posts to your picture in the database, the newly created thread is automatically added to your watch list and you'll see it on the ATP homepage.

OK, TYVM! Awesome.
