And immediately before it, paste this code:

<script src='http://code.jquery.com/jquery-latest.js'

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

//Larger thumbnail preview

$(&quot;ul.thumb li&quot;).hover(function() {
$(this).css({&#39;z-index&#39; : &#39;10&#39;});
$(this).find(&#39;img&#39;).addClass(&quot;hover&quot;).stop()
.animate({
marginTop: &#39;-110px&#39;,
marginLeft: &#39;-110px&#39;,
top: &#39;50%&#39;,
left: &#39;50%&#39;,
width: &#39;174px&#39;,
height: &#39;174px&#39;,
padding: &#39;20px&#39;
}, 200);

} , function() {
$(this).css({&#39;z-index&#39; : &#39;0&#39;});
$(this).find(&#39;img&#39;).removeClass(&quot;hover&quot;).stop()
.animate({
marginTop: &#39;0&#39;,
marginLeft: &#39;0&#39;,
top: &#39;0&#39;,
left: &#39;0&#39;,
width: &#39;100px&#39;,
height: &#39;100px&#39;,
padding: &#39;5px&#39;
}, 400);
});

//Swap Image on Click
$(&quot;ul.thumb li a&quot;).click(function() {

var mainImage = $(this).attr(&quot;href&quot;); //Find Image Name
$(&quot;#main_view img&quot;).attr({ src: mainImage });
return false;
});

});
</script>


Now click Save Template

Step 2. Adding The Gallery To your template.

Go to Layout >> page elements and on your template’s sidebar, header or footer Click on ‘Add a Gadget‘.

then Select HTML/Javascript

A new window will appear, in title box Type your gallery title, and in content area Copy and Paste the next code

<ul class="thumb">
<li><a href="#"><img src="picture 1 Link" alt="" /></a></li>
<li><a href="#"><img src="picture 2 Link" alt="" /></a></li>
<li><a href="#"><img src="picture 3 Link" alt="" /></a></li>
<li><a href="#"><img src="picture 4 Link" alt="" /></a></li>
</ul>

Now click Save 

Then instead Of picture 1 Link Type Your Image Url,

and if you want to make the image link to another page or url instead of # Add the target url.

Each time you want to add a new image to the gallery, just repeat this code.

<li><a href="URL 1 #"><img src="picture 1 Link" alt="" /></a></li>

That’s it.
