What's wrong with this simple jQuery?
<p>I'm targetting the image in the following HTML</p>

<pre><code>&lt;h1 class="logo-site-name"&gt;
  &lt;span id="logo"&gt;
    &lt;a href="http://some.link"&gt;
      &lt;img src="http://www.other.com/some.gif"&gt;
    &lt;/a&gt;
  &lt;/span&gt;
&lt;/h1&gt;
</code></pre>

<p>And I'm attempting to replace the image with the following code, but it isn't working. Am I selecting &amp; modifying correctly?</p>

<p><code>
$('#logo').children('img').attr('src', 'http://www.domain.com/image.gif');
</code></p>
