Spews is a basic wallpaper manager that enables you to automatically update your desktop wallpaper on a configurable schedule.You can specify one or more folders as the source of your wallpaper images and the program will automatically cycle through the images in those folders. You can configure to switch wallpapers every X seconds, minutes or hours, and there is also an option for manual switching via keyboard hotkey.Spews also comes with a feature that automatically suspends the wallpaper switching if it detects any process names you configure in the Exclusions section. This can be useful, for instance, when running games that have graphics issues if the wallpaper is changed.
