Music Artist fanart

Im trying to wokrout what I need to do to get the most fanart for artists showing when playing full screen music.

I have artist slideshow add in and runnin that it looks like it is pulling down heaps of fan art, yet when I choose artist + viewing it seems to only scroll between two images. Choosing artist only shows a different fanart again.

Is there some instruction as to what add ons (if any) are needed and any settings to allow the most variety of fanart to show?

Thanks
