Your registered Supporters are the ones sending you these photos.
They have an App on their phone called the Lumin Supporter's App. This app allows them to send you photos from their phones and link specific Facebook photo albums straight to your Lumin Screen.
Whenever they upload photos and images in these shared folders through their Facebook accounts, it would then be automatically sent to your Lumin Screen.
This is a quick way of sharing photos of friends and family almost instantly so you can share the fun times as they happen.
