I'm not quite sure what the problem is. I've built 4 or 5 Windows 10 KODI systems, all with Artist Slideshow. In this case, it's using Transparency! on KODI 18.9. I've left it running playing music for known artists for hours and not one image was displayed. I've compared all the settings to my main KODI box and I haven't found a difference.

Do I have to give it a kick start or what?

Skins sometimes have a different way of kicking off artist slideshow (or enabling it).  I'd be happy to look at a debug log (with Kodi and AS debug logging on), but if it's only happening with Transparency! you might check in the support thread for that skin.

The Transparency forum didn't offer any solution to the problem. I looked at the AS Wiki and there's this instruction:

"If you want to manually add support for AS to an existing skin, you need to add/update a few things in MusicVisualization.xml.
To run the script:
<onload>RunScript(script.artistslideshow)</onload>"

My questions are these:

Which MusicVisualization.xml (What is the path?)
Do I need add this line to the script or edit a pre-existing line?
