Using bliss with iTunes - viewing embedded art in iTunes
This is down to the way bliss embeds art into MP3s. The ID3v2 specification describes some information that should be stored with embedded art.
iTunes requires the MIME type of the art to include a subtype. Previously, bliss would embed art with just the MIME type "image". However, iTunes requires a more specific MIME type, such as "image/jpeg" or "image/png" depending on the type of the image.
I've fixed this, and the new build is under test by the customer in question. bliss now fully populates the MIME type, and for good measure populates the picture type of the art to 'type 3' - cover (front).
The build with this fix in will be available in ten days. Any other users wanting to try it out should get in touch and I'd be pleased to forward it onto them.
