I would say, rather, that moOde doesn't handle cover art as thoroughly as it could.
Keep in mind that Id3V2.3 is not a formal standard but an informal specification, no matter what its authors call it. Implementors support some parts, ignore others, and corrupt their usage of it as they see fit, since there is no recognized organization which certifies products against it.
Secondly, the Id3 world is only a subset of the metadata markup world. Don't discount Vorbis/Comments, used in FLAC files, or ISO14496, used in MP4 files, and there are others.
Basically, for embedded images the existing moOde code (/var/www/coverart.php) uses PHP library routines to extract the first image they find in an audio file. In most cases I've seen, there is only one embedded image and it is the front cover artwork for the album. I think, historically at least, there has been pressure not to stuff too much imagery into MP3 files in order to keep the file size down.
I'm sure Tim would consider a PR from some enterprising developer which forces the moOde routine to take only the front cover image assuming it has been so identified.
And let's never forget my favorite Id3V2.3 Picture Type: $11, which is a "bright colored fish".

Kent
