Well yes, of course it does.
If you'd like other software / hardware developers to support album art within ogg vorbis, do *not* do it that way.

What's about this proposal now? If it turns out that it doesn't harm the majority of both software and hardware players, it would be by far the easiest way which supports *all* requested things about album art.

I can gladly provide such an ogg vorbis file for testing if that's OK.

I think we should reach a consensus about the album art issue; people have been waiting for it long enough. An easy solution like the comment-embedded binary coverart structure would soon be implemented by most ogg vorbis players and taggers etc. as soon as it's "official".

Cheers
Mathias
