Tagging images

Is there a way to tag images?

When I upload an image, I can edit its data on the admin panel, and it even gets its own “page”, where it’s possible to comment. Is there a way to add tags (or a category) to this page?

This way I intend to use a tag like “photo of the day” or something similar.

If there’s no way to add tag/category, maybe there’s another way to add what I’m looking for?

Thanks in advance.
