new Image or new Image()

[Nimerion]

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"){

setupRoll(document.images);

}

}

}



function setupRoll(thisImage){

thisImage.outImage = new Image();

thisImage.outImage.src = thisImage.src;

thisImage.onmouseout = rollOut;



thisImage.overImage = new Image();

thisImage.overImage.src = "images/" + thisImage.id + "_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..
