I see that Artist Slideshow does load all those images into an image group starting at line 10587:
The last line is where the actual image to display is set for the skin. Artist Slideshow doesn't actually display the image, it just sets a property so that skins that support Artist Slideshow can display the images. If you're not seeing the images, there is either an issue with Kodi reading the image or your skin is doing something unexpected. If you aren't using the default Estuary skin, you should try that. It will at least tell you if it's a skin problem or something else.
