Dynamically changing source of image - jQuery
<p>I got the following code:</p>

<p><strong>HTML</strong></p>

<pre><code>&lt;div class="image"&gt;
    &lt;img src="http://ecx.images-amazon.com/images/I/41ghiuvjdvL._SL75_SS50_.jpg" /&gt;
&lt;/div&gt;

&lt;br /&gt;

&lt;div class="photo"&gt;
    &lt;img src="http://profile.ak.fbcdn.net/hprofile-ak-ash2/27520_119569768054263_2432_q.jpg" /&gt;
&lt;/div&gt;​
</code></pre>

<p><strong>JS</strong></p>

<pre><code>// getting src of bottom image
var bottomSrc = $(".photo img").find("src");

// getting src of top image
var topSrc = $(".image img").find("src");

$(".photo").click(function() {
    // changing sources
    // topSrc.attr("src", bottomSrc);
    // topSrc.replaceWith(bottomSrc);
    topSrc.replace(bottomSrc);
})​
</code></pre>

<p><a href="http://jsfiddle.net/LyMZd/1" rel="nofollow">Fiddle</a></p>

<p>When the bottom image is clicked, I want the <code>src</code> of the top image to be replaced with the bottom image's <code>src</code>, so that both images are the same.</p>

<p>Why does the supplied code does not work?</p>
