Yeah, there are lots.

Here's one from The Javascript Source

Just change and/or add lines like this
image_list[image_index++] = new
imageItem("http://javascript.internet.com/img/image-cycler/01.jpg");
to your own images

<html>
<head>

<script language="javascript">
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;
document[place].title = 'image' + image_index
var recur_call = "rotateImage('"+place+"')";
setTimeout(recur_call, interval);
}
</script>
</head>
<body onload="rotateImage('rImage')">

<center>
<img name="rImage"
src="http://javascript.internet.com/img/image-cycler/01.jpg" width=120
height=90>
