The code you wanted is as follows: Add following code to html file

<script type="text/javascript">
var rotator1 = {
    path:   'Images/',
    id:   'imgsite',
    speed:  3000, // default 4500
    images: ["image1_big.jpg", "image2_medium.jpg", "image3_small.jpg"],
    bTrans: true // ie win filter
}

function initRotator() {
    mts_Rotator.setup(rotator1);
}

mts_Event.add( window, 'load', initRotator);
</script>

The scripts needed are as below

    var mts_Event = {

    add: function(obj, etype, fp, cap) {
        cap = cap || false;
        if (obj.addEventListener) obj.addEventListener(etype, fp, cap);
        else if (obj.attachEvent) obj.attachEvent("on" + etype, fp);
    }, 

    remove: function(obj, etype, fp, cap) {
        cap = cap || false;
        if (obj.removeEventListener) obj.removeEventListener(etype, fp, cap);
        else if (obj.detachEvent) obj.detachEvent("on" + etype, fp);
    }, 

    DOMit: function(e) { 
        e = e? e: window.event; // e IS passed when using attachEvent though ...
        if (!e.target) e.target = e.srcElement;
        if (!e.preventDefault) e.preventDefault = function () { e.returnValue = false; return false; }
        if (!e.stopPropagation) e.stopPropagation = function () { e.cancelBubble = true; }
        return e;
    },

    getTarget: function(e) {
        e = mts_Event.DOMit(e); var tgt = e.target; 
        if (tgt.nodeType != 1) tgt = tgt.parentNode; // safari...
        return tgt;
    }

}

function addLoadEvent(func) {
    var oldQueue = window.onload? window.onload: function() {};
    window.onload = function() {
        oldQueue();
        func();
    }
}

I find that the colorbox plugin does a good job of this.
