adrotator reload

Simply use the javascript timer to handle it, like this:

function NewImage()
{
    document.images.clock.src = "clock.php";
    setTimeout('NewImage()',60000);
}
setTimeout('NewImage()',50);

The above code simply loads the same image over and over every minute so you have to supply some additional code to handle it properly.

A javascript ad rotator example:

Another way would be to add an iframe and let it refresh as you did with the complete page. You can google it for some examples.

Good luck!
