John's Background Switcher: Switch your desktop wallpaper periodically
Screenshots
Do you get bored of your background wallpaper? John's Background Switcher periodically changes the background image on your computer to ensure it's always looking fresh.
John's Background Switcher allows you to configure when you want to change the background (such as every hour or every day) and you can specify which pictures to use in a number of ways. For example, one way is to select a list of specific pictures on your computer. Alternatively, you can direct John's Background Switcher to point at a particular folder such as 'My Pictures' and it will select random pictures from there.
It doesn't stop there though. John's Background Switcher also allows you to use Flickr to choose pictures by person, tags, sets, or just randomly. There are several options that allow you to customize the look of images, such as by narrowing down the pictures or increasing the quality of those chosen.
John's Background Switcher is a simple but effective way to choose different backgrounds from a huge range of sources.
