Bing is known for its greatest images. Daily it beatifies its home page by a new image. “Bing my lockscreen” is a Windows 8 app that lets you set one of the eight latest Bing images as your lock screen wallpaper manually or automatically. Interested users go this app page from their Windows 8 PC and install it. After installation, run the app from Windows 8’s Modern UI and select an image, and then set it as lock screen image (right click and select Set Lockscreen).
In addition, Bing My Lockscreen allows you to automatically have your lock screen updated daily with the latest image from Bing (this feature will be available in the upcoming update).
