Background image resize with windowsize possible??

Once I found a way to make a background image in a td scale with the td,
when window was made larger or smaller.
I (so stupid) did not use it in the end and never wrote down the code.

I am all into divs instead of tables, and would like to do the same thin now in a div.

The example of the page is here:
www.c10web.com/fa/fa2.htm

The left side with the picture in it is suppost to be all over the left side (it is seperated in 2 one side with the picture = A
and one side with the text = B
The backgroundimage is suppost to be 100% of A in height and width.

The code used for A =

   #links {
	margin: 0 0 0 0;
    padding: 0;
    width: 50%;
	height: 100%;
    float: left;
    overflow: hidden;
    background: #a75eac url(afbeeldingen/foto_groep.jpg) no-repeat 0% 0%;
  }

I posted a question about this site before and these problems are kind of solved now. So i am eager to get it all done.[/code]
