“Overall, it is a nice and simple application to get new and interesting wallpaper on your PC daily. The best part is that it’s a very lightweight application and will not at all affect the performance of your PC.”

“If you are not the kind of user who likes to stare at the default wallpaper that ships with the Windows operating system, a plain solid color, or a custom photo wallpaper that never changes, you may be interested in Picturethrill, a new program to automatically download and set wallpapers from various sources including Microsoft’s Bing wallpaper of the day”
