To add photos to multiple frames at once, open the Aura App and click into "Photos," "Albums," or "Collections." Next, tap on "Choose Photos" - or if you'd like to add an entire Album or Collection, click "Add All." Then click "Add Photos" at the bottom of the screen to pull up your list of frames. Choose the frames you would like to add the photos to from your list of frames by tapping the check box next to each frame, then click "Add Photos" at the bottom of the screen. That's it!
