Tilfældige billeder i et slideshow

Jeg har et element, der viser billeder i et slideshow. Hvordan får jeg den sat (og er det muligt), så den viser billederne i tilfældig rækkefølge for hver upload?

Koden er:
[code]
openside(" ");
?>
<table border="0" cellspacing="0" cellpadding="0" height="400" align="center">
<tr>
<td>
<script language="JavaScript1.2">

var variableslide=new Array()

//variableslide[x]=["path to image", "OPTIONAL link for image", "OPTIONAL text description (supports HTML tags)"]


variableslide[0]=['/images/assensvej.jpg', 'http://assensvej.dk', 'tekst']
variableslide[1]=['/images/groennerammer.png', '', '']
variableslide[2]=['images/Hund.png', '', '']








//configure the below 3 variables to set the dimension/background color of the slideshow

var slidewidth='513px' //set to width of LARGEST image in your slideshow

var slideheight='385px' //set to height of LARGEST iamge in your slideshow, plus any text description
var slidebgcolor='##EDEDED'

//configure the below variable to determine the delay between image rotations (in miliseconds)
var slidedelay=4000

////Do not edit pass this line////////////////

var ie=document.all
var dom=document.getElementById

for (i=0;i<variableslide.length;i++){
var cacheimage=new Image()
cacheimage.src=variableslide[i][0]
}

var currentslide=0

function rotateimages(){
contentcontainer='<center>'
if (variableslide[currentslide][1]!="")
contentcontainer+='<a target="_blank" href="'+variableslide[currentslide][1]+'">'
contentcontainer+='<img src="'+variableslide[currentslide][0]+'" border="0" vspace="0">'
if (variableslide[currentslide][1]!="")
contentcontainer+='</a>'
contentcontainer+='</center>'
if (variableslide[currentslide][2]!="")
contentcontainer+=variableslide[currentslide][2]

if (document.layers){
crossrotateobj.document.write(contentcontainer)
crossrotateobj.document.close()
}
else if (ie||dom)
crossrotateobj.innerHTML=contentcontainer
if (currentslide==variableslide.length-1) currentslide=0
else currentslide++
setTimeout("rotateimages()",slidedelay)
}

if (ie||dom)
document.write('<div id="slidedom" style="width:'+slidewidth+';height:'+slideheight+'; background-color:'+slidebgcolor+'"></div>')

function start_slider(){
crossrotateobj=dom? document.getElementById("slidedom") : ie? document.all.slidedom : document.slidensmain.document.slidenssub
if (document.layers)
document.slidensmain.visibility="show"
rotateimages()
}

if (ie||dom)
start_slider()
else if (document.layers)
window.onload=start_slider
