Artist Photo Slideshow

Put as audio visualization a slideshow when playing music a photo-stream of album-cover & artist-pictures retrieved from Flickr. Use Artist-name from DB as search-string from Flickr, retrieve the result set, and display as slideshow with nice animation. This requires a solution where photo-player & music-player can both play at the same time.
This should be considered as a fall-back solution on windows (when graphic card makes it impossible to load audio-visualization through Gstreamer).
