Can I hide guest photos or make them available for all guests to view?

Absolutely! As the host, you're in control of how you want the gallery to function for your needs.

You can choose to display or hide the gallery from your guests. To hide the gallery, simply login to your host dashboard and navigate to the 3-dot "More" icon on the right hand side and then select "Edit". From there, select "Manage Settings" and you'll be able to switch "Allow guests to view the gallery" to "No" which is the first setting.

If you switch photo sharing off, guests will only be able to see photos that they have uploaded. You may even choose to hide photos from guests initially, then review and delete any unwanted images / videos, before switching this back on, to make the gallery available for all guests to view and enjoy.
