If the bride and groom included our HD online gallery in their project, they can send out link for everyone to view. All our WeddingMix App + Cameras Packages include an HD online gallery. For our WeddingMix App only customers this option can be added to a project for only $25. 

The bride and groom are the only one's who have access to the photos and videos sent into their individual project to respect their privacy. If you see the word 'Done' next to the thumbnails in the My Media screen of the app after uploading then they definitely are in their project.
