So I'm trying to loop through this array and change an image source every few seconds. Right now I have an onload event calling a setTimeOut method which should change the image 5 seconds after the page has loaded I would think, but it is doing it instantly. What is the problem? Here is my code:

<html>
<head>
    <title>Ad Rotaror</title>
    <script type="text/javascript">

        var ads = new Array(4);
                  ads[0]='promo1.gif';
                  ads[1]='promo2.gif';
                  ads[2]='promo3.gif';
                  ads[3]='promo4.gif';
                  ads[4]='promo5.gif';

        function change()
        {
            if(i > 4)
                i = 0;

            document.images[0].src = ads[i];
            i++;
        }
    </script>
</head>
<body>
    <img src="promo1.gif" onload="setInterval(change(), 5000)" />
</body>
</html>

Change 'change()' to 'change'. You are calling the function immediately.
