Now I'm curious too. I'm really not sure what Mp3tag does.

Correct, this is not implemented yet. Can you please file a bug report
on about it?

Note that this is only an issue for FLAC. Cover art in FLAC files is
stored in a separate block type METADATA_BLOCK_PICTURE. On the other
hand, Vorbis Comments store cover art in a vorbis comment named
"METADATA_BLOCK_PICTURE" (according to the latest recommendation),
which is something you already can do.
