How do you make it so that falling images fall in the back of the page content rather than over it?

Don't think it is possible. Never seen it before. You might be able to choose a background that looks like falling stars or whatever. But I don't think it is possible. I have looked it up on Google and found nothing. Sorry

It's ok....
I know it's possible though....it's a feature on Geocities....I'll have to find out their code...
