Commenting on Caps?

First, sorry if I'm posting this in the wrong place. Seemed like the best place to put it.

What I'm asking about is if comments could be made on individual caps like Deviant Art has. I often don't comment on anything as I would then have to specify which cap I'm trying to make a comment about. Can this feature be added to this site? If comments could be made and other's read on individual caps, more comments would be made.

Comments have been consolidated in the Forum so that it's not necessary to dig down into the library to see them on individual items. If there were more comments, along with significantly more contributing volume, and the site structured more like a blog, your suggestion would be more feasible, but we won't rule it out either.
