salve, ho scaricato il menu dock dalla sezione java

la mia domanda è questa:

è possibile fare in modo che quando non si passa con il mouse, l'icona visibile sia 64*64 mentre al passaggio del mouse diventa 128*128 ??


<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript" src="js/interface.js"></script>
<link href="style.css" rel="stylesheet" type="text/css" />
<!--[if lt IE 7]>
<style type="text/css">
.dock img { behavior: url(iepngfix.htc) }
</style>
<![endif]-->
</head>
<body style="background-image: url('')">
<h1>Menu stile dock</h1>
<div class="dock" id="dock2" style="position: absolute; left: -1px; bottom: 413px">
<div class="dock-container2">

</div>
</div>
<script type="text/javascript">

$(document).ready(
function()
{
$('#dock2').Fisheye(
{
maxWidth: 90,
items: 'a',
itemsText: 'span',
container: '.dock-container2',
itemWidth: 60,
proximity: 120,
alignment : 'left',
valign: 'bottom',
halign : 'center'
}
)
}
);

</script>

Grazie
