Auto Refresh Gallery or Galleries?

Is there a way to auto refresh a specific gallery or all galleries?

Example: I sometimes upload photos to a gallery live from an event. Guests will be browsing the gallery on their phones or tablets looking through photos throughout the night. Currently they need to refresh the page to see new photos. I'm looking for a way to "auto refresh" the webpage for these type of events.

Any suggestions would be appreciated especially if it works!
