A:Answer You can add a caption that will be visible on the frame screen, although be aware that if you add a caption to a photo that you have added to multiple different frames, that caption will be visible on ALL of the different frames even if the users are different. Also any user can add a caption not just the one who added the photo, and that caption will still be visible across all the different frames, even the ones that user does not have access to.
You cannot otherwise manipulate the photos on the frame.
You cannot search for specific photos.
You can use the Aura app to select photos from your iPhone to add to each frame.
