Another innovation you could bring, would be a note for voting on other notes. Like a way to attach a ⭐ to the image (it would actually be a star-note attached to the image-note).

Then people could see notes/images ranked by star-notes, maybe with a focus on their WoT's star-votes.

Or you could use the highlighter NIP as a basis for it, and allow a comment along with the star.
