Here's a 2-step process that works for me (on an Apple computer -- but should work on a PC too).
1. Click (or double click) on any of the photos you want in that group. It should open as an individual photo in your browser.
2. Look in the bottom right corner of that page -- it has 4 symbols, and the 3rd one is a down arrow. That's the "download" arrow. Click on that, and the photo should download to your computer as a jpeg. Place the photo in a folder, or onto your desktop.

Hope that works for you.
