Como abrir links ao clicar

Queria que,ao clicar em um título,abrisse um link.

Aqui está a demonstração: http://www.addyosmani.com/resources/shinetime/

Repare que ao clicar nas imagens pequenas,aparece sua forma maior, e ao passar o mouse,o título da imagem aparece. Enfim,queria que ao clicar nesses títulos,abrisse um link. Apenas isso.

Aqui está o código JavaScript :

<script type="text/javascript">
$(document).ready(function()

{

/Your ShineTime Welcome Image/

var default_image = 'images/large/default.jpg';
var default_caption = 'Welcome to ShineTime';

/Load The Default Image/

loadPhoto(default_image, default_caption);

function loadPhoto($url, $caption)

{

/Image pre-loader/

showPreloader();
var img = new Image();
jQuery(img).load( function()

{

jQuery(img).hide();
hidePreloader();

}).attr({ "src": $url });

$('#largephoto').css('background-image','url("' + $url + '")');
$('#largephoto').data('caption', $caption);
}

/ When a thumbnail is clicked/
$('.thumb_container').click(function()
{

var handler = $(this).find('.large_image');
var newsrc = handler.attr('src');
var newcaption = handler.attr('rel');
loadPhoto(newsrc, newcaption);

});

/When the main photo is hovered over/
$('#largephoto').hover(function()
{

var currentCaption = ($(this).data('caption'));
var largeCaption = $(this).find('#largecaption');

largeCaption.stop();
largeCaption.css('opacity','0.9');
largeCaption.find('.captionContent').html(currentCaption);

largeCaption.fadeIn()

largeCaption.find('.captionShine').stop();
largeCaption.find('.captionShine').css("background-position","-550px 0");
largeCaption.find('.captionShine').animate({backgroundPosition: '550px 0'},700);

Cufon.replace('.captionContent');

},

function()

{

var largeCaption = $(this).find('#largecaption');
largeCaption.find('.captionContent').html('');
largeCaption.fadeOut();

});

/ When a thumbnail is hovered over/
$('.thumb_container').hover(function()
{

$(this).find(".large_thumb").stop().animate({marginLeft:-7, marginTop:-7},200);
$(this).find(".large_thumb_shine").stop();
$(this).find(".large_thumb_shine").css("background-position","-99px 0");
$(this).find(".large_thumb_shine").animate({backgroundPosition: '99px 0'},700);

}, function()

{

$(this).find(".large_thumb").stop().animate({marginLeft:0, marginTop:0},200);
});

function showPreloader()

{

$('#loader').css('background-image','url("images/interface/loader.gif")');
}

function hidePreloader()

{

$('#loader').css('background-image','url("")');
}

});
</script>

O HTML (exemplo):

<div class="thumbnailimage">
<div class="thumb_container">
<div class="large_thumb"> <img src="images/thumbnails/sample1.jpg" class="large_thumb_image" alt="thumb"> <img alt="" src="images/large/sample1.jpg" class="large_image" rel=" Tíulo das imagens">
<div class="large_thumb_border"> </div>
<div class="large_thumb_shine"> </div>
</div>
</div>
</div>  

Daí queria colocar um href='' ''
