[Plugin: HTML5 MP3 Player with Playlist] Image updates on song name click but not automatically

Hello. I have an XML file with various albums in it. Each has an image. Clicking on the song title updates the thumbnail, but when the player goes to the next song automatically, the thumbnail doesn’t update. Can you give some insight in to how to update the code to make the thumbnail update automatically?
