Saving backgrounds before uploading

Thanks for making the STILL BEST skin for Kodi, Please Mr Silvo I need help desperately. No matter what I try,(and I’ve tried everything) this wizard, that wizard. Converting my physical folders to special universal backups on and on. I need someone to tell or show me where to put my menu backgrounds so they show up on the other side.I have my build updated to Krypton with everything working but my backgrounds won’t come out on a different device. I even tried copying them all to the Android/data/org.xbmckodi folder but just dropping them in there didn’t work either. Can I just hash a new folder into that directory and store them there? This is making me want to walk in front of a train. Many thanks for all you do…..
