2 questions about background images

Hey All,

Thanks to Juggledad I've been playing around with a large background image for my site. But, now some other issues are coming up. I've searched this forum as well as a Google search, but can't find anything.

Question #1:
How can I get a second image in the background? I have one large, centered image at the top, but I want to add a repeating image underneath it to give the illusion that the drop shadow on the right is continuing down. For the second image I simply cut a few pixels from the bottom of the large image.

If there isn't a way to do this then I'll probably remove the drop shadow and just stick with a plain white box for the background.

Question #2:
Is there any way to rotate through background images, similar to how the header can rotate through images each time you refresh the page?

Thanks!!!!!!!!!

Here's an example of a repeating middle-image: www.sandhillpress.com. It looks like a small slice of notebook image keeps repeating until it hits the footer.
