Information box on mouseover

Is there anyone who knows how Voddler made the informa开发者_StackOverflow中文版tion box that appears when the mouse is hovering over the movie covers?

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.

I can't acess Voddler (I'm outside the US) but from reading what you are asking, I would suggest using jQuery with qTip
