How do I copy my pics on icloud to an external hard drive? I'm trying to figure out how to back up my pictures on iCloud to an external hard drive.  Do I seriously have to do this one pic at a time?
I opened Photos on my iMac running High Sierra 10.13.5. I then selected multiple photos using shift-click. Now go to the file menu and select Export and follow the directions. The last step lets you choose where to save the photos.
