I nearly did not consider Soloslides at all, because Google Photos is so prominent in the name.
Also "Camera Roll" is one specific selection within Apple/iCloud photos so I also nearly looked over the option that is the perfect fit for my use case: iCloud backed shared album. I don't need to expose my entire photo collection to the iPad if I share the photos in an album shared with an account dedicated for this purpose that has access to only this album.
Naming: drop Google Photos or add Apple/iCloud
