Adding the advancedsettings.xml file is the first step. Then you need a source of artwork so lets assume you are using local artwork. Once the advancedsettings.xml file is added with the artwork entries, then the movies need to be Refreshed back into the library. When this is done, Kodi will rescan the local folder and load any extra images it now discovers.

Have you done that? Provide a Debug Log if you have and it is not working.

Okay, thanks to your getting it through my thick head that I needed to refresh the movie so that the art would be loaded, I've finally overcome my stubborn mental block, and got it "working".  :-)

Things I now think I understand, but please correct me if I'm wrong:

1. That the files with the generic names are not going to work in the extrafanarts folder.
   
2. That the extrafanart files will need to be moved into the folder with the movie, and named with the moviename-farnart#.jpg
   
3. That the movies will then need to be refreshed in order for the new images to be discovered
   
4. That, by doing so, the images are NOT copied locally?  Yes?  No?  Maybe? 
   
5. That I will write a quick little script to cycle through my movie & tv shows folders, and rename / move the files that are currently in the extrafanart folders.
   
6. That, for new movies / tv shows that I add, I will investigate the settings in Ember Media Manager to see if there is a way to handle the extrafanart naming / folder placement there instead, and, if not post it as a suggestion to the author.
   
7. That, if 6 is a no-go, I will, instead, implement my rename script going forward for new movies / tv shows.
   

Again, thanks to you @Karellen (as always) and @mikeSiLVO for taking the time to assist as I delve too deep into the minutiae, shift my thought paradigm from what I think, to what truly is.
