How do you get animated online pictures to animate on your desktop background?

You cannot. Desktop is a single image which would cause problems if you made it animate.


Windows 98 allowed you to disply the desktop as a web page, which allowed animation.

Vista ultimate allows you to play an mpeg move on the desktop background.

Windows 7 and Vista allows the use of gadgets which can be made to display animated images behind active windows.

I believe windows 7 has the option to display background as a webpage too.
