To download your photo, just click the button on this page which will download the Zipped photo file to your Download folder.

Safari will probably just open the zipped file for you automatically, and show it to you in Preview.
If not, to open it, simply double click the Zipped file and your Photo will open up next to it. It’s about a 30 Meg file.

Then trash the zipped file if you like.

Note: If you don’t know where the zip file downloaded to, just search Colorado-Mountains.jpg.zip or Colorado-Mountains
