jQuery traversing dom to get to an element
<p>I am having a hard time figuring out how to correctly and most efficiently traverse the dom to select the element I need.</p>

<p>Basically I need it where when the select statement is changed, it would change an element's CSS to display block.  Initially it is display NONE.</p>

<p>I currently am trying to use prevAll() but obviously it isn't working...</p>

<p>Please see <a href="http://jsfiddle.net/8G4Aj/" rel="nofollow">http://jsfiddle.net/8G4Aj/</a> for live sample</p>

<p>HTML:</p>

<pre><code>&lt;div class="wrapper"&gt;
    &lt;div class="more-wrapper"&gt;
        &lt;img src="http://someimage.png" alt="image" /&gt;
    &lt;/div&gt;    
&lt;/div&gt;

&lt;div class="another-wrapper"&gt;
    &lt;div class="some-wrapper"&gt;
        &lt;form&gt;
            &lt;select&gt;
                &lt;option value="1"&gt;1&lt;/option&gt;
                &lt;option value="2"&gt;2&lt;/option&gt;
            &lt;/select&gt;
        &lt;/form&gt;
    &lt;/div&gt;
&lt;/div&gt;
</code></pre>

<p>JS:</p>

<pre><code>$("form select").change(function() {
    $(this).prevAll('img').css("display","block");
});
</code></pre>

<p>Thanks!</p>
