Portable 100dof Wallpaper Rotator

Designed as the portable edition of 100dof Wallpaper Rotator, this is a simple-to-use software application that allows you to configure a automatic system for changing the desktop wallpaper. It offers support for BMP, ICO JPG and PNG images.

Since there is no setup pack involved, you can drop the program files in any part of the hard drive and just click the executable to launch the app. Another possibility is to keep it stored on a USB flash drive, in order to directly run it on any PC with minimum effort an no previous installers. Plus, it doesn't modify the Windows registry settings.

Based on a standard window with a neatly organized structure, the interface lets you immediately dive into the configuration procedure.

You can indicate a folder whose containing images will be automatically taken into account for wallpaper rotations, provided that their file types are supported by 100dof Wallpaper Rotator.

It's possible to include or exclude subfolders, follow any existing shortcuts to files or folders, specify the image order (alphabetical, unsorted or random), pick the wallpaper style (tile, center, stretch), preserve the original aspect ratio, stretch images from the inside or outside, customize the background color, as well as enable or disable automatic color selection.

You can ask the tool to remove the current wallpaper, and to re-apply it. All changes are applicable with the click of a button.

Unfortunately, 100dof Wallpaper Rotator doesn't integrate options for filtering images from the specified directory (e.g. by file type or date), for previewing the wallpaper rotation mode before applying settings, or for setting the rotation frequency.

Unsurprisingly, the app had minimal impact on computer performance in our tests, running on low CPU and RAM. It didn't hang, crash or prompt error dialogs.

All in all, 100dof Wallpaper Rotator delivers a simple method for setting up an automatic system for rotating the desktop wallpaper. However, it lacks many practical options.
