Information box on mouseover
<p>Is there anyone who knows how <a href="http://www.voddler.com/movie/browse/" rel="nofollow">Voddler</a> made the information box that appears when the mouse is hovering over the movie covers?</p>

<p>What I want is to display an information box when the mouse hovers over an image in my gallery. There is a neat solution on www.voddler.com/movie/browse and I was wondering if anyone knows how they have done? I did not realize that voddler not work worldwide, therefore, I attach a screenshot.</p>
