How could I change this from an autoplay loop, to an onMouseOver event?

This works exactly how I want it to, I just can't figure out how to make it occur on a mouse over, instead of auto playing when the page loads? Here's the code.

<script language="JavaScript1.1">
var slidespeed=3000

//specify images
var slideimages=new Array(
	"images/1.jpg",
	"images/2.jpg",
	"images/3.jpg")

//specify corresponding links
var slidelinks=new Array(
	"http://www.example1.com",
	"http://www.example2.com",
	"http://www.example3.com")

var newwindow=1 //open links in new window? 1=yes, 0=no

var imageholder=new Array()
var ie=document.all
for (i=0;i<slideimages.length;i++){
imageholder[i]=new Image()
imageholder[i].src=slideimages[i]
}

function gotoshow(){
if (newwindow)
window.open(slidelinks[whichlink])
else
window.location=slidelinks[whichlink]
}
</script>

<a href="javascript:gotoshow()"><img src="images/4.jpg" name="slide" border=0 style="filter:blendTrans(duration=3)" width=97 height=100></a>

<script language="JavaScript1.1">
var whichlink=0
var whichimage=0
var blenddelay=(ie)? document.images.slide.filters[0].duration*1000 : 0
function slideit(){
if (!document.images) return
if (ie) document.images.slide.filters[0].apply()
document.images.slide.src=imageholder[whichimage].src
if (ie) document.images.slide.filters[0].play()
whichlink=whichimage
whichimage=(whichimage<slideimages.length-1)? whichimage+1 : 0
setTimeout("slideit()",slidespeed+blenddelay)
}
slideit()
</script>
