there seems to be a bug steven. when playing a playlist i found that the when the next track plays it still rotates pictures from the previous artist and not currently playing artist. after restarting it updates to the currently playing artist but it stays rotating pictures from that artist.
just in case i have the something wrong this is the element im using.
element type="Gallery" tags="artist:local" x="5" y="355" width="310" height="200" aspectRatio="zoomKeep" fillColor="0,0,0,0" fade="0.0" interval="30" bdr="255,10,10,10"></element>
