Image Rotation - where do I put in pics

[wxdqz]

I am new to javascript, found this to rotate images but can't figure out where my images should be in this script. Everything I've tried gives me an error.

Hope you can help,
Janet


<!-- Begin
var interval = 2.5; // delay between rotating images (in seconds)
var random_display = 1; // 0 = no, 1 = yes
interval *= 1000;

var image_index = 0;
image_list = new Array();
image_list[image_index++] = new imageItem("http://javascript.internet.com/img/image-cycler/01.jpg");
image_list[image_index++] = new imageItem("http://javascript.internet.com/img/image-cycler/02.jpg");
image_list[image_index++] = new imageItem("http://javascript.internet.com/img/image-cycler/03.jpg");
image_list[image_index++] = new imageItem("http://javascript.internet.com/img/image-cycler/04.jpg");
var number_of_image = image_list.length;
function imageItem(image_location) {
this.image_item = new Image();
this.image_item.src = image_location;
}
function get_ImageItemLocation(imageObj) {
return(imageObj.image_item.src)
}
function generate(x, y) {
var range = y - x + 1;
return Math.floor(Math.random() * range) + x;
}
function getNextImage() {
if (random_display) {
image_index = generate(0, number_of_image-1);
}
else {
image_index = (image_index+1) % number_of_image;
}
var new_image = get_ImageItemLocation(image_list[image_index]);
return(new_image);
}
function rotateImage(place) {
var new_image = getNextImage();
document[place].src = new_image;
var recur_call = "rotateImage('"+place+"')";
setTimeout(recur_call, interval);
}
// End -->
