hvordan laver jeg link til de to billder?

<script language="javascript">

var delay=2500 //set delay in miliseconds
var curindex=0

var randomimages=new Array()

    randomimages[0]="h_img/1.jpg"
    randomimages[1]="h_img/5.jpg"
var preload=new Array()

for (n=0;n<randomimages.length;n++)
{
    preload[n]=new Image()
    preload[n].src=randomimages[n]
}

document.write('<img name="defaultimage" src="'+randomimages[Math.floor(Math.random()*(randomimages.length))]+'" width="150" height="150" border="1"> ')

function rotateimage()
{

if (curindex==(tempindex=Math.floor(Math.random()*(randomimages.length)))){
curindex=curindex==0? 1 : curindex-1
}
else
curindex=tempindex

    document.images.defaultimage.src=randomimages[curindex]
}

setInterval("rotateimage()",delay)

</script>
