You can do a right-click on the photo itself, then look at Properties and tell what site the photo came from. If you copy and paste that url into your window at the top, it will take you to the site that it came from.
However, the photo was just sitting there on that site with a bunch of photos of various people and no explanation. I don't think the photo was originally at that site, they got it somewhere else.
I think I have seen it somewhere else with an explanation but for the life of me I cannot remember where I have tried the main sources of photos that I know of but cannot find it.
