ps -the link has cropped him off, but if you click on the picture you'll see him in all his glory(?!)
This picture is not only cropped, don't expect that the link is working long!
It looks like a
Goggle Photo picture link, but Google do not allow external linking of pictures. See help page of
Google Photos.
There is a share option, but the users need to go to the Google pages to see it.
External linking was a feature of
Picasa, but now it is not possible to add photos to it. I think that was one of the main reason to replace
Picasa by
Photos.
