Random Image with onclick popup link

[admin]

Hi
I'm setting up a random script to select from 5 different images, and they each have their own url they will link to when clicked. This works fine. The problem I'm having is when clicking on these random images when they load, having the url they link to be in a popup sized window. I know about onclick events, etc, but tieing all these things together is what's screwing me up. Any help would be appreciated. Thanks.
Here's my code so far.

<script language="JavaScript">

var imagenumber = 5 ;
var randomnumber = Math.random() ;
var rand1 = Math.round( (imagenumber-1) * randomnumber) + 1 ;
images = new Array
images[1] = "http://10.1.1.168/Hunter/consumerSite/media/home/teasers/airmax.jpg"
images[2] = "http://10.1.1.168/Hunter/consumerSite/media/home/teasers/ezblade.jpg"

images[5] = "http://10.1.1.168/Hunter/consumerSite/media/home/teasers/ezglass.jpg"
var image = images[rand1]

links = new Array

var link = links[rand1]// -- End Hiding Here -->
