If an image is flagged & deleted, it already gets a red mark under it, saying why it was deleted. Which makes sense.
So why not, if an image is flagged & resolved; It gets a green mark instead?
It could list the flag reason, and that it was resolved, and whom by.
It might cut down on multi-flagging if people can see that it's already been flagged and resolved.
As it is; When an image is flagged and resolved now, sometimes it lists that it has been flagged and resolved, sometimes it just does not, making it look like no one ever flagged it in the first place. Which could lead to even good-faith users re-flagging it because they are unaware of it's previous resolution.
