When you click on a funny wallpaper image you will be running a wallpaper installer program for that particular funny background. The desktop wallpaper installer simply installs the funny wallpaper on your desktop as you would manually. There is no software for tracking or any other purpose other than to make it easy for visitors, particularly novice computer users, to install these fall backgrounds easily. You will get two security messages. Simply click on the Run button to respond to both messages. Click here to see messages you can expect to see if you're running Microsoft Windows XP.
