WallpaperChanger

WallpaperChanger can prove useful for automatically modifying the desktop wallpaper once every a few minutes, seconds or hours, giving you a helping hand in customizing the appearance of your computer.
One of its main advantages is that it offers you the possibility to create multiple themes, which are groups of images that are used as desktop backgrounds.
The application runs silently in the system tray, enabling you to access all its options from the context menu. As such, you can quickly switch to the next or the previous wallpaper, modify the used theme, deactivate or activate WallpaperChanger.
The 'Settings' section is where you can configure the application's behavior. It enables you to browse for individual images you want to include within a picture set or import whole directories.
Wallpapers can be modified sequentially or randomly and the image can be automatically tiled, stretched, centered or resized to fit the screen dimensions, while keeping the original aspect ratio.
Additionally, you can customize the background color and adjust the change frequency, which can vary from a few seconds to a few days. To make things easier, WallpaperChanger enables you to set a custom hotkey for changing the wallpaper.
The application can prevent CPU overloading by cancelling its tasks when a user-defined threshold is exceeded. Moreover, you can instruct it to to the same when the PC remains in idle mode for more than a few minutes or seconds.
WallpaperChanger can change the desktop wallpaper for you at predefined time intervals, saving you the trouble of performing this operation manually whenever you get bored with the current background image. The variate customization options and the ease of use make it worth a try.
