In Don's album the right click thing works, but for me it does not in the Stovebolt bucket.
But what does work:
When scrolling through the photos (arrow on each side of the picture) and you get to the picture you want, in the top right (sometimes in the photo itself) there are 4 grey boxes (star, arrow in a circle, magnifying glass, and gear), click on the magnifying glass to view just the photo. Once the image reappears the right click trick works. Then just use the back button to get back to the slide show.
Don't know why but that is how I got the group photo to my computer.
