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?


openside(" ");

<table border="0" cellspacing="0" cellpadding="0" height="400" align="center">

<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
