Show Label With Scriptaculous

The goal is to make the "label" appear when the main div is clicked.


HTML4 Strict Code:

<div class="photo" onclick="showlabel(this);">
    <img src="names_02.jpg" alt="image" width="561" height="52" />
    <div class="label"><img src="names_01.jpg" alt="image" width="590" height="52" /></div>
</div>


JavaScript Code:
function showlabel(div) {
    var label = div.childNodes;
    new Effect.BlindRight(label[1]);
}

This will affect the first <img>, but I want the <div> surrounding the second <img> to get the effect.
