jquery image change doesnt work
<p>The following code should work but I cant seem to find the problem why it doesnt work, I am testing it with google chrome</p>

<pre><code>&lt;html&gt;
    &lt;head&gt;
        &lt;script type="text/javascript" src="js/jquery_1.7.1_min.js"&gt;&lt;/script&gt;
        &lt;script type="text/javascript"&gt;
            $('#unos').click(function() {
                $("#tre").attr('src', '/012/11/image2.jpg');
            });
        &lt;/script&gt;
    &lt;/head&gt;

    &lt;body&gt;
        &lt;img id="tre" class="aligncenter" title="images" src="/012/11/image1.jpg" alt="" width="940" height="207" /&gt;
        &lt;input id="unos" type="submit" name="change_src" value="change image" /&gt;
    &lt;/body&gt;
&lt;/html&gt;
</code></pre>
