Fixed random background?

[ajackwithoneeye]

I used this code: http://javascript.internet.com/bgeffects/random-background.html , for a random background image. But I'd like it to be fixed at the bottom right hand corner, and I can't seem to figure out how. Any suggestions?

Try this:
document.body.style.background = "url(path/to/backg.gif) no-repeat fixed bottom right";
