I wish the site displayed the artist after hovering over an image. Similar to FA's system, both for simple convenience and blacklisting purposes. It would be easier to discover artists and recognize their style.
I'm sure every frequent user of this site has been browsing a tag and found something they found... upsetting. Not "That's a weird fetish" weird; more like "Oh God maybe I should clear my browser now". In the latter situation, I know I'd prefer to be able to instantly know the artist without having to go to the image's page. I could quickly check their wiki or blacklist them. This feature would make the general experience more enjoyable.
