You're welcome to save these pictures to your computer and use them for your wallpapers. If your computer crashes, you won't lose the pictures if you have an external hard drive. They back up everything that you have downloaded, or ever single picture you have taken. Lets say that you downloaded ever picture on this page and your computer crashed. A way to recover this type of mishap would be to get a data recovery done on your computer instead of going through and saving all the pictures again. (Just a little bit of my helpful information.)
