Hi all,

After years of half-arsed trying every 6 months, I sat down and got my unraid kodi mysql databse working.
I upgraded my UNRAID a few weeks back and promised my wife I would sort it. We used trakt but one day it went mad and marked everything as watched and won't reset unless I wipe everything. That was enough of a boot to get it fixed for me.

Unraid server 6.5.3
MariaDB docker
Kodi 17.6 on Main PC
Kodi 17.6 on RP3
Kodi 17.6 on mediaPC

First step new install on Main of Kodi, add shares, mark them all as watched etc.
Export to unraid drive as back up

Setup MariaDB in docker on Unraid.
Log in qith mysql studio and set users correctly.

Main import the export. Loginto MariDB and confirm there is the right number of lines in the table to shows and movies.
New Kodi build on RP3 AND MediaPC. Copy over advancedsettings.xml and source.xml
All machines can see the same thing, and pick up when it's watched, how far in to resume etc!!!! 
But...none of them except Main have any thumbnails or art at all.

I tried copying my thumbnails13 and thumbnails folder from Main to the others but nothing.

Now I'm stumped! I tried searching but I couldn't find the right info.
