Here’s their story for The Force Awakens about Captain Phasma. These pictures don’t typically tell much in ways of the story. They do tend to tell us subtle bits of the stories I’ve found though. Like an example this one of Phasma seems to be the rubble of Maz’s castle. There was another of Kylo without his mask and snowtrooppers. So I think there’s bits of truth within the pictures but it’s not absolute truth.
I think this new one shows Luke on location where the Jedi Temple burned. I think we’ll be getting more to the story.
