I like collecting wallpapers and changing the background image of my Windows desktop quite frequently.
However, sometimes I have a slight problem: I have so many beautiful images that I don't know which one to choose. Fortunately this problem can be solved with ThetaWall, a simple tool that can create immediate collages, with the photos saved in a selected folder, and use them as desktop background.
ThetaWall doesn't require installation: simply extract the contents of the ZIP archive into the folder with your wallpaper collection and launch the executable file. The program will place an icon on the System Tray, from where you can access its main functions. Also, a double click will change the wallpaper automatically.
Configuration options in ThetaWall include the possibility to use just one image or create a collage with several of them. Every time you generate a new collage, ThetaWall grabs a bunch of different images and uses a different layout. It's great to have such a wide variety of designs, but I'd also like to have the chance to select the photos and layout myself.
ThetaWall supports dual-screen installations and can add a calendar to one of them. You can also create a screensaver with the same images you use as wallpaper.
If you have a large collection of wallpapers, you can show them all off with ThetaWall, a simple tool that creates desktop collages automatically.
