I have not seen this used by any MP3 ripper that is available to me. And this is a very inefficient way to store images, every MP3 file has the image embedded. I prefer the folder.jpg concept most hosts and MP use. Specially since if I need to extract the image from the mp3 to a file and then add it as a tag to the UPnP info it is a very crappy sollution. I am willing to add the folger.jpg that MP uses for display to the tags.MP3 and stuff doesnt really support Ablum art I believe, sure I would be able to embed th property with a link to a folder.jpg if present in the folder. Thats how MP works I believe.
this is incorrect.
with ID tags 2.0 the is the ability to insert a small jpg inside the mp3 as meta data. itunes for instance uses this to access album art
