Adding hanging image to bottom of Global Body_Background or the Footer?

[Jain Farstrider]

I would like to know how to get a second image in global>body_background to work with the first one.

What I'm asking is that the first one is content-body repeat-Y and have the second one to only be at the bottom to cap the end.

Just image a image background with a graphic boarder all around the sides, but you wish the border to also be at the top and bottom too but that will not work if the image ends up repeating-y obviously.

So to fix that, have one image with just the boarder on the left and right side repeat-y and at the very top have a second image with just the top boarder cap it and a third image with a bottom boarder to cap the bottom, viola you have a content background with a boarder along the edges and none running through the middle.

Excuse my crappy Photoshop but i have made an exact example of what I want to do below. Obviously the curtain at the bottom will need to go below the vBulletin version and GMT time text. If it can be attached to the footer instead and still have the curtain go below the text, that would work fine as well.
