Artwork not appearing

I’m using djay for Mac, and not one single piece of artwork shows, even though I’m one of those people who tags all their music. djay for iPhone displays the artwork fine, but the Mac app doesn’t see it.

I’m using Mountain Lion, although this has been the case for me since using Lion.

Any ideas?

Here also so it’s a recurring problem with the software. Any ideas Algoriddim?

Same here, it stopped appearing after installing Mountain Lion
