Your screensaver might show you random pictures from your My Pictures folder – that’s pretty common. The disadvantage to that is you are seeing the same pictures over and over.
What if you could see different pictures every time your screensaver kicked in? Random pictures from OTHER people? That is what you can do with Loopy (get it free here).
Download Loopy, open the .zip folder, and drag the file loopy.exe to your desktop. Then double-click it to install.
When Loopy is your chosen screensaver, you will see random pictures pulled from Flickr, a popular online photo storage site.
