Io farei una cosa del genere:

codice:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Costa Daniele - pittore sculture</title>
<script language="JavaScript" type="text/javascript">

function addbookmark()
{
bookmarkurl="http://www.webalice.it/costaalessio/home.htm"
bookmarktitle="Costa Daniele - pittore sculture"
if (document.all)
window.external.AddFavorite(bookmarkurl,bookmarktitle)
}

</script>

</head>

<body>
<div id="DIV_casa">
[img]casa.jpg[/img]</div>
</body>
</html>
