It sounds like a very particular use case. I don't know of an extension that does this.

From what I understand, you want to give a piece of data (e.g. "Description") to an uploaded file and then have that data used whenever the file is used. So, if a user uploads a picture of a pig, they can designate "Wilbert" as the description that will always be shown with the image's thumbnail.

Is that right?

I think something like this could be accomplished using templates, though, or even a bit of JavaScript. It would take a little time to implement, though.
