I just tested embedding covert art to an APE file with Mp3tag. MC displayed it fine. In addition to jpg I tested also png, because I didn't know if MC supports the png format. Also png displayed correctly.
klavier,
If you can reproduce the problem with a recent MC build (install the latest as Jim instructed) I would like to see a sample file. I attached a very small APE file (in a zip package). Could you please download it, unzip, add cover art, upload it somewhere, and post a link? (Assuming you can reproduce the problem with the sample file.)
Log in to the forum if you can't see the attachment.
