Go to Jon Miner's Web site.
It works like an online shopping site... add the photos you want to your cart.
Caution - downloading the whole collection or even a
major part will take forever and besides may not work!
When you've selected all you want to download, go to the drop-down box near
the upper right corner and choose "Download in Zip" and click "Go".
Choose a location to save the download file and save to disk.
You should then be able to extract the downloaded file into individual pictures.
