<div class="swipe">
	<img src="img/swipe-annotation.png" height="30" link="bookmark"><img src="img/swipe-favourite.png" height="30" link="favourite"><img src="img/swipe-pencil.png" height="30" link="annotate"><img src="img/swipe-email.png" height="30" link="email"><img src="img/swipe-tweet.png" height="30" link="tweet"><img src="img/swipe-facebook.png" height="30" link="facebook">
</div>

In your JS (assuming you have jQuery, otherwise will need to adjust accordingly):

	$(".swipe img[link]").click(function() {
		document.location.href = $(this).attr("link") + "://" + $(this).attr("link");
	});
