I think it would be nice if there was an option to 'privatize' comments made to images in the gallery. The option could be global, to be set by the artist who created the post, or local, to be set by the commenter.

Why? When I'm commenting, I feel like the others are ease-dropping on my comment, or that I am ease-dropping on their comments. Also, privacy can create intimacy which is an attractive and bonding force for the two participants.

The forum moderators should still be able to see all the comments during edit mode, but not otherwise.
