How Do I change the Website Background with Links?

[appleguy6142]

Hey!
I want to make a Javascript that allows you to change the Backgound from White to Black

I have two images - black.gif and white.gif

When I click on on black.gif i want the Background to change to Black and Visa Versa

How can I do that?

<img src="black.gif" onclick="document.body.style.backgroundColor='#000';" alt="black" />
<img src="white.gif" onclick="document.body.style.backgroundColor='#fff';" alt="white" />
