Please see the example below of how a Slideshow can be displayed on big screens:
All you need to do is connect a device to the big screens, it will then read all the photos of the server instantly and display in the slideshow.
Lack of internet connection will always be a problem if you would like to use this option. With slow internet, photos are displayed in the loop with new ones being added into a slideshow as soon as uploaded to the server.
