Slide information popup

[Chaim]

I need to display information about slides in the following slide show. This script allows me to click on the picture and open a new link in a browser. Is there anyway to use it to popup a window on the same page?

var photos=new Array()
var photoslink=new Array()
var which=0

//define images. You can have as many as you want:
photos[0]="questions/intro.jpg"

//Specify whether images should be linked or not (1=linked)
var linkornot=0

//Set corresponding URLs for above images. Define ONLY if variable linkornot equals "1"
photoslink[0]=""
photoslink[1]=""
photoslink[2]=""
