Not clear. You talking of on-hover event?

If you use jQuery, it can be very easy:

HTML

<html>

<head>
	<title>Test</title>
	<meta http-equiv="content-type" content="text/html;charset=utf-8" />
	<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>
	<script>
		$(function() {
			$('#box').hover(function (e) {
				$(this).fadeTo('slow', 1.0);
			}, function (e) {
				$(this).fadeTo('slow', 0.4);
			});
		});
	</script>
</head>

<body>
     <div id="box" style="background-color: rgba(0, 0, 0, 0.4)">Picture and label</div>
</body>
</html>
