Tools for a happier life gives you a deal you cannot refuse. Simply add a few lines of HTML code to your site. This will display an auto-updating thumbnail of a desktop wallpaper. When users click on this thumbnail, a new window will open from where the wallpaper can be downloaded for free. Once you add the code to your web page, your site is linked to from a PR4 (current PR) page as a friend/supporter. So not only are you able to give away free stuff to your site visitors but also are able to get a free high PR backlink.
