I see "cover_art_presence" in release_meta, which would be perfect for this. Except it is always sent "absent", there doesn't seem to be code setting it anywhere. Should cover_art_presence be set in the cover art edits and did we not implement this yet? Or is this field some old relic which shouldn't be used?

(assigning to oliver as he should be able to answer my question above

Hmm, you don't have the update_release_coverart trigger on cover_art_archive.cover_art? That's in 20120216-caa-metadata.sql.

fixed in commit 6f98a3d56db1dc125724a87231446b7be1991e26

but the messages I used may be a bit subtle, please suggest improvements:

I would suggest a "View other images" link to the cover art tab after "No front cover image available"

reopened to make sure the previous comment from nikki is implemented.

Fixed in 940e338.
