The photo in question shows Dalton Rappatoni, a member of the boy band IM5, and it was posted to a GR group by what was almost certainly a fan of the band. It's not clear why BWP Media chose to file a lawsuit rather than simply file a DMCA takedown notice, but it does raise questions about whether this is a legitimate case or an example of copyright trolling.
I have yet to hear back from Goodreads, but odds are this is a lawsuit that will go nowhere fast. This situation is clearly covered by the DMCA, meaning that Goodreads is almost certainly not liable for the possible infringement committed by a user. Just about the only way Goodreads might be liable is if they screwed up their DMCA notice process, and I seriously doubt that happened.
Curiously enough, I'm pretty sure the photo in question is still visible on Goodreads. It's one of a handful of photos that have been uploaded to an album.
