Okay, I have started an album on Google Photo. Good user interface- no need to sign in or anything- it recognizes your computer and you go right to album. Had trouble at first, went to a selected photo, and copied the URL from address window in my browser. That did not work!
I then went back to image, and right clicked on image. One option was copy image location. I selected that, went back to forum, selected the picture icon, and did a control-v in address window of the pop-up screen. That worked fine. I am now going to switch to Google Photo.
