Library editor: manually import album art?

[bufordsharkley]

It appears (correct me if I'm wrong) that album art is imported automatically when Discog import is executed, but isn't possible to do in any other way

In addition to the album art being pretty neat in general, it's also useful to a new project to auto-compose album art + review + track listing + track runtimes for producing new CD-Rs for our ~digital-only releases

Being able to import album art would be nice, for this reason.
