A reminder …
All of the pictures below were taken from the above 15.5 mile walk. They were all taken in the direction of the walk, i.e. not looking behind me.
Your task is to tell me the order in which the pictures were taken (there are only 720 possible options!).
All exif (camera recorded) data has been removed from the images and they all bear the same time-stamp. So no help there.
Good luck.
