How to make changing backgrounds in Windows 7.

I have a couple of desktop backgrounds I want to use for my desktop, but I want them to change at random, much like the preset backgrounds it comes with.
I'm running windows 7 Home Premium 64bit.

right-click desktop, click properties..then click desktop background at the bottom, and select multiple check boxes for the themes you want. then after that, click save theme, and give it a name you want for easy access.

I'm pretty sure if you put the picture into your My Pictures folder, you can then right-click on it and choose the option "Set Picture as background" or something. It can be in another folder as well. Just not on the desktop.

he wants to have it to where the background changes automatically on a time frame set by the user (him) my way does that perfectly, that's how i got multiple cat pictures on mine! ^_^

Thanks. It works
