Step-by-step procedure

Connect the tablet to your laptop

Plug the USB-C end of the cable into the tablet and the USB end into the laptop.

Open the tablet storage on the laptop and paste your image into the Pictures folder. The wallpaper menu picks images up from there.

On the tablet go to Settings, then Universal, then Wallpaper. Your image is now in the list.

I did this on the Thinkscan 689BT. The same steps apply to the Thinkscan 689BT Pro, Mucar 892BT and Mucar 892BT Pro.
