When an album art is added, it technically adds to the source file and not just to RealPlayer. Therefore, if and when added, the album art will show up if you play with any media player. Can you please send us a screenshot of what is not working correctly?
I recently paid to upgrad to the latest edition of Player and by far, my primary use is to manage my music. I have learned how to change the Album Art on downloaded songs that it is missing from but there is no facility to save the new art once it has been added. How does one save the changes, keep the songs in their place in the play list, and not have to forever be changing it?
