Does anyone know if there's a tagger for OS X that can add album art to FLACs?

I tried Media Rage, and it won't, and S. Booth's Tag doesn't handle images. Is there anything else?

I just added art to a FLAC file with Media Rage 3.4.2 and it appeared to have stuck. I then dragged the file to Max's Convert window (it appeared in the artwork drawer), converted to AAC and iTunes correctly displayed it.

I'm guessing you're using an earlier version of Media Rage ?

Thanks for the response. No, I'm not: mine's 3.4.2, too.

I'll try again with some other files.

EDIT

OK. I've found I can do what you did, ffooky -- add an image to "a FLAC file".

I had been using the "QuickEdit (Multiple File)" window. However, I don't really want to edit all my FLACs singly. And it seems Media Rage can't edit art in a set of FLACs -- IOW, a whole album at a time.
