Not quite. I find that if I change my preferences to exclude "Rich Text" posting, I can get the forum to accept the image portion of the posting text generated by RYM. That means cutting the first half of the RYM-text to use as the link part of my post, and adding "http:" to the second half of the RYM-text to create the album cover image. Doing that is okay for me, but it's too cumbersome a solution for most anyone else who isn't obsessed with it. In fact, it's hardly a solution at all.
I'll keep looking. The answer is out there, somewhere.
