jQuery : manipulate width and height of an img tag
<p>How do I change the height and width of an image in and unordered list with jQuery</p>

<pre><code>&lt;ul id="files"&gt;
   &lt;li&gt;&lt;img src="1.png" /&gt;&lt;/li&gt;
   &lt;li&gt;&lt;img src="2.png" /&gt;&lt;/li&gt;
   &lt;li&gt;&lt;img src="3.png" /&gt;/li&gt;
&lt;/ul&gt;
</code></pre>

<p>My css :</p>

<pre><code>ul#files li img
{
width: 100px;
height:100px;
}
</code></pre>

<p>I've tried this :</p>

<pre><code>$('ul &gt; li &gt; img').width('300');
$('ul &gt; li &gt; img').height('300');
</code></pre>
