Comments on photos in albums

[DonMuncy]

I was looking at some photos in my album and shifted down and noticed that some folks had posted comments on them. I was unaware that someone could comment on photos. Some of these comments are years old, and asked questions about the pics. Not knowing they existed, I did not respond. Perhaps a system could be set up to notify the album "owner" when a comment is posted, so responses  can be timely made.
