How to put javascript as a background?

I am rather new to this. I found a javascript that would change an image each month. I want to place this script as a background image inside the table of a page.

Here’s the script I found:

<script language=javascript>
/*
Changing image or text each month of the year
Author: Narayan Chand Thakur

*/
<!–hide

nctDay= new Date();
var month = nctDay.getMonth()+1;

var numberofimages = 12;
images = new Array(numberofimages+1);
images[1] = “<img src=’yourimage.jpg’>”;
images[2] = “<img src=’yourimage02.jpg’>”;
images[3] = “<img src=’yourimage03.jpg’>”;
images[4] = “<img src=’yourimage04.jpg’>”;
images[5] = “<img src=’yourimage05.jpg’>”;
images[6] = “<img src=’yourimage06.jpg’>”;
images[7] = “<img src=’yourimage07.jpg’>”;
images[8] = “<img src=’yourimage08.jpg’>”;
images[9] = “<img src=’yourimage09.jpg’>”;
images[10] = “<img src=’yourimage10.jpg’>”;
images[11] = “<img src=’yourimage11.jpg’>”;
images[12] = “<img src=’yourimage12.jpg’>”;

document.write(images[month]);
//–>
</script>

And here’s the part of my website I would like to alter:

<TABLE width=”50″ height=”65″ cellpadding=”0″ cellspacing=”0″ background=”calendar_dec.bmp”>

<TBODY>
<TR>
<TD align=”center” valign=”bottom” height=”20″>
<a href=”http://www.meh.com/” alt=”NONE” target=”_blank” style=”text-decoration : none;”>

I want the image (the javascript) to go where the background=”” tab is. There is a clock script after that, that will show the date on the image.

Is this possible or am I deluding myself?

Thank you for taking the time to read this!
