Thanks to blog comments by J.B. Nicholson-Owens and Panzi, Magnatune now has cover art embedded in FLAC and OGG files. In a previous blog entry, I announced that we had album art in our MP3 and AAC file downloads but hadn't been able to do the same for FLAC and OGG files.
Support for album art varies among audio players that support FLAC and OGG files. I tested "totem" and "vlc" and both worked for me.

Just as with our MP3 and AAC files, I'm using a 300x300 pixel JPG as the artwork source, which is a good compromise between quality and file size.
Rhythmbox is currently crashing on startup on my Ubuntu install, and Amarok crashed X windows on me, so I wasn't able to test those two players.
