Wallpaper Timer

Wallpaper Timer is a tiny widget that allows you to set an unlimited number of pictures to switch and apply as wallpapers, based on a user-defined time interval. It can be effortlessly installed and set up, regardless of the user's skill level.
The interface of the application is represented by a small frame that you can move to any position on the screen, with the help of the mouse cursor. It shows thumbnails of all pictures from the default folder and allows you to navigate them.
By opening the Options screen, you can alter the default folder containing the pictures you want as wallpapers, include subfolders and enable shuffle mode.
But you can also make the images fit the screen or appear tiled or centered. The time interval for the transitions can be defined in seconds, minutes or hours.
Thanks to the default options provided by the operating system, you may also increase the frame size, make it stay on top of other windows or adjust its opacity level.
Wallpaper Timer barely uses CPU and system memory, so it does not interfere with the runtime of other currently running processes. It has a good response time and works smoothly, without making the operating system hang, crash or pop up error dialogs; we haven't encountered any problems throughout our evaluation. Thanks to its intuitive layout and overall simplicity, Wallpaper Timer's features should be seamlessly figured out, even by novices.
