How to set up images background and thumbnails for additional items in the menu? I also have separate movis, tv, kids movies and kids tv  but i do not know how to configure images to display only from those items? Menu must by set up as playlist or source folder?

I use Emby Server and the Emby plugin with Kodi, Libraries in Emby are pulled to Kodi and each Library can be setup as a home screen menu item. Images, thumbnails, and backgrounds are normally pulled from the Emby server and displayed for the correct library so if I select Kids Movies I get a thumbnail for a kids movie, the movie logo on the background and a background image from that movie. At the moment the images and thumbnails and logos are mixed between the libraries.

Is the Emby plugin something you installed on Kodi or Emby side?
Do you also use the "Smart Shortcuts" for your Emby folder?

Thanks,

Yes using smart shortcuts and Titan by default setups the images and thumbnails.
