Facebook is a social networking site that allows you to post a picture and have links to friends. On Facebook, you can view all your friends photos as a grid. To do this, select “My Friends” from the left menu, and then select “—-” from the drop down menu next to the text “Show.” Normally it will show “All Friends” or “Recently Updated” friends, but if you select to show “—-” then you get the grid. These images here are scaled down because I have so many friends it would take too much space to show everyone in full size.
