Q818 How can I combine image highlighting with the dynamic tooltips script?

<SCRIPT TYPE="text/javascript" LANGUAGE="JavaScript"><!--
if (document.images) {
    var image1on = new Images();
    image1on.src = 'image1on.gif';
    var image1off = new Images();
    image1off.src = 'image1.gif';

    var image2on = new Images();
    image2on.src = 'image2on.gif';
    var image2off = new Images();
    image2off.src = 'image2off.gif';
}

function show(object,image) {
    if (document.images) {
        document.images[image].src = image + 'on.gif';
    }
    if (document.layers && document.layers[object] != null)
        document.layers[object].visibility = 'visible';
    else if (document.all)
        document.all[object].style.visibility = 'visible';
}
function hide(object,image) {
    if (document.images) {
        document.images[image].src = image + '.gif';
    }
    if (document.layers && document.layers[object] != null)
        document.layers[object].visibility = 'hidden';
    else if (document.all)
        document.all[object].style.visibility = 'hidden';
}
