And so to the next 'problem.'

All the photos from her old phone, are backed up to Google, somewhere in the cloud.

The new phone has folders entitled Gallery and Photos. Inside Gallery on the new, are the few photos she has taken with the new phone. Inside Photos, are all the photos from her old phone. I am assuming that these photos are a link to Google in the cloud rather than stored on the hardware. But there seems to be no way to move them from wherever they are to the Gallery.

Specifically, how can I move (restore?) the photos to Gallery?
