Right Alignment not working in IE

Hello, I'm hoping that this will turn out to be something I'm missing due to lack sleep... LOL

Please check out http://www.wtvgames.com/messedup/ (please note the code was from an IE "Save As", not the way I format it, however all tags and attributes are there.)

Anyhow in IE, I cannot get the image to go all the way to the right side of the screen. In Firefox it displays fine. The idea is to have a page that will stretch out if you are larger than 800x600. It pushes it to the right if I fill up the center table cell (main content area), however not all pages will have content this size. The center cell is the only one needing to stretch horizontally.

I'm still learning the "proper" way to use CSS for all attributes, so any suggestions using that method is preferred.

Thank you in advance.
