Expandidng SWF To A Special Way

I want to expand my SWF to the 100% of my window, but always sticked to the left, for example:

www.visionstreetwear.com

Note that the SWF’s size will always be as the size of your window, but also note that when you contract the window by the sides, the left side of the SWF will always be showing and the height of the SWF will be equal to the height of the window…

I tried downloading the scripts and the whole structure of that site and try it with my own SWF, but it didn’t work. When I contract my window by the sides, it makes my SWF smaller by all proportions.

Take a look and compare…

Any ideas on how I can fix this?

THANKS in advance!
