We love Windows 7 inbuilt wallpaper rotation, keeps the desktop lively. If you love the simplicity and save some battery by using static wallpapers, skipping Live wallpapers, this one might be for you.
Wallpaper Rotator offers a free wallpaper swapping using photos from a local directory or your Flickr account.
All you have to do is select the wallpapers that rotate on a specified time interval — every half hour, hour, six hours, day, or week. Picasa, Facebook integration is coming soon.
Compatible with all android phones since Android 1.5, try it out.
If you prefer offline wallpapers only, try Wallpaper Switcher instead, it lets you rotate wallpapers at specified minutes, hours, days.
And if static wallpaper isn’t your thing, Create your own Live wallpaper
