Kør kun slideshow én gang

Hej Alle..

Jeg har dette udemærkede slideshow..

Jeg vil nu gerne have det til kun at køre én gang.. Hvordan gør jeg det?

<script language="JavaScript1.1">

var slidespeed=1000
var slideimages=new Array("_01.jpg","_02.jpg","_03.jpg","_04.jpg","_05.jpg","_06.jpg","_07.jpg")
var slidelinks=new Array("#","#","#","#","#","#","#")
var newwindow=0 //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>

<img src="_01.jpg" name="slide" border="0" style="filter:blendTrans(duration=3)" width="750" height="370">

<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>
