When your Gallery is in Presentation Mode it will automatically switch between media items at designated intervals ranging from 1 second to 1 minute.

To display your Gallery at a live location you will first need to enable Presentation Mode by going to the Advanced tab of your Gallery setup and selecting Allow presentation mode.

You can also determine how frequently your Gallery should switch between media items under Presentation tick interval.

You can then open your Hosted Gallery Page on the device you want to display your Gallery on and press the 'F' key to enter Presentation Mode, or the 'H' key to enter Presentation Mode with the Gallery Header hidden.

Presentation Mode also has a live refresh feature, so new media will be included if your Gallery is showing Most Recent.
