Background images of the application are added from this page.
If there is one picture in the list, this picture cannot be deleted and its activity cannot be removed.
Each picture added by the user is saved as two different pictures at 1920×1080 and 1280×720 in order to adapt to different TVs in the hotel. The required size version is shown on the relevant TV.
If there is more than one active picture, the background picture changes each time you navigate on the Hotel TV.
If there are multiple background images in the list and you delete or deactivate the only active image, the first image in the list is automatically selected by active.
