If you have a large collection of photos, one of the best ways to show them off is by using them as desktop wallpaper. But if you can't be bothered to change your wallpaper manually, then you could use Caledos Automatic Wallpaper Changer.
This app takes over the wallpaper management on your system, updating the Windows desktop background automatically according to the specifications you set in the program's configuration menu. You can choose the image folder you want the program to use, select the time interval between each new wallpaper and also set the preferred layout.
Caledos Automatic Wallpaper Changer features a wide range of options for choosing the wallpaper time interval, from one minute to one month, and including also the possibility to change it with each log-on. Image folders can be easily filtered so that the program doesn't use a specific sub-folder.
On the downside, Caledos Automatic Wallpaper Changer only includes two layout options (centered or full screen) and doesn't allow you to set it separately for each picture. What's more, the center layout includes a tagline with the program's URL that can't be removed.
Despite a few minor flaws, Caledos Automatic Wallpaper Changer is still a very handy way to renew your Windows wallpaper.
