I want to apply a (hover over) style to the element below, but I can't figure out the CSS syntax. Here is my structure (from what I see in Firebug):

<table class= "products products-table">
<tr class= {varies}>...


<td class="highlight first last product-cell">
  <div class="foo">
    <a><img .../>
      <span>
        <img { APPLY STYLE WHEN HOVERING OVER THIS IMG ITEM } />
      </span>
    </a>
  </div>
</td>

Note: I'm going to want to put a different style for <td class="highlight last product-cell"

Thanks
