Can guests download from the gallery?

Yes, if the host of the gallery has enabled this in their settings, guests will see a little download icon appear in the corner of each photo. This will download the full-resolution version of the photo/video, not the thumbnail view you are viewing in the gallery (this is compressed for a faster viewing experience).

If this feature appears disabled then hosts can activate it by logging into their host dashboard and on the right side of the event, click the three dots to open the action menu and select "Edit". Then select 'Manage Settings' on the left side to toggle this feature on.
