Random image script

[Gaverick]

I'm trying to make a script to generate a different logo everytime a user visits a website, so far i have the following code:

<script type="text/javascript">
function get_random()
{
    var ranNum= Math.floor(Math.random()*5);
    return ranNum;
}
</script>

<script type="text/javascript">
function genlogo()
{
   var whichlogo=get_random();

    var logo=new Array(6)
     logo[0]="anysite.png";
     logo[1]="anysitenew.png";
     logo[2]="anysitecandy.png";   
     logo[3]="anysiteclass.png";
     logo[4]="anysiteweb2.png";
     logo[5]="anysiteplas.png";
  
    return logo[whichlogo]);
  }
 </script>

How would i call this is the HTML to display the image link that has been generated?

Edit: adding document.write('<img src="'+genlogo()+'" border=0></a>'); to the end makes the image on the page but does not position it where i want, how would i position the image?

Edit: i've got it sorted, thanks for the help
