For attraction photos you will need to have Bluetooth turned on on your phone. As others have said, you may wish to take note of approx time you ride as not all photos will automatically appear and you may need to request they locate photos.
For photos taken by a CM, you will be given a plastic card (as far as I know. Someone please correct if this is old as we use MBs.) Each time you have photos taken the CM will scan your plastic card. You will link that card to
MDE and your photos will be there.
