Problems with proportions of images

[henkroos]

I have a page on my website that shows images fullscreen. But it messes up the proportions of all the images. How can I prevent that from happening.

The webpage can be viewed at http://www.henkroos.nl/nieuw/index.php
The code i use is:

<SCRIPT LANGUAGE="JavaScript">
<!--

//set image paths
src = ["plaatjes/001.jpg", "plaatjes/002.jpg", "plaatjes/003.jpg", "plaatjes/004.jpg", "plaatjes/005.jpg", "plaatjes/006.jpg",
"plaatjes/007.jpg", "plaatjes/008.jpg", "plaatjes/009.jpg", "plaatjes/010.jpg", "plaatjes/011.jpg", "plaatjes/012.jpg",
"plaatjes/013.jpg", "plaatjes/014.jpg", "plaatjes/015.jpg", "plaatjes/016.jpg", "plaatjes/017.jpg", "plaatjes/018.jpg",
"plaatjes/019.jpg", "plaatjes/020.jpg"]

//set duration for each image
duration = 4;

//Please do not edit below
ads=[]; ct=0;
function switchAd() {
var n=(ct+1)%src.length;
if (ads[n] && (ads[n].complete || ads[n].complete==null)) {
document["Ad_Image"].src = ads[ct=n].src;
}
ads[n=(ct+1)%src.length] = new Image;
ads[n].src = src[n];
setTimeout("switchAd()",duration*1000);
}
function doLink(){
location.href = url[ct];
} onload = function(){
if (document.images)
switchAd();
}
//-->
</SCRIPT>

Can anyone please help me?

Was that humor? If so, i really didn't get the clue. Maybe someone else can help me with my problem? Someone who's not Tommy Cooper!!
