    Hi there..
    I’m new at javascript and I’ve just watched a tutorial about the rolloers..

    window.onload = rollInit;

    function rollInit(){
    for(var i=0; i if(document.images.parentNode.tagName == "A"){

    function setupRoll(thisImage){
    thisImage.outImage = new Image();
    thisImage.outImage.src = thisImage.src;
    thisImage.onmouseout = rollOut;

    thisImage.overImage = new Image();
    thisImage.overImage.src = "images/" + + "_on.gif";
    thisImage.onmouseover = rollOver;

    function rollOut(){
    this.src = this.outImage.src;

    function rollOver(){
    this.src = this.overImage.src;

    In this example, I’ve first realized, that in the setupRoll function where I have “new Image();” if i write “new Image;” is the absolutely the same thing.

    But I can’t find anywhere an explanation of this..
