The cloud

Apparently this photograph has gone from my 'phone into one of these cabinets, then up a mast, then off to some cloud or other, then back down to another mast, anywhere in the world, then to another box and then onwards to some-one's 'phone or computer. All in a split second and without me having any clue whatsoever as to how it happens.
What a wonderful, be it troubled, world we do live in!
