Images that are not saved in the DCIM folder do not appear on the Discover Photo category.
When a memory card is inserted in a camera, a folder labeled DCIM is created by the camera in which all the photos are saved. This TV only reads photos that are saved in the DCIM folder. To ensure proper viewing of the photos, copy the DCIM folder first to the root folder of your USB device and saved the photos in it before connecting it to the TV and accessing the Discover Photo category.
