Slideshow doesn't work

Hi,

I think this plugin should be able to do exactly what I’m looking for, but for some reason it won’t work! As you can see on http://christinerode.com/wp/what-food-looks-like/, the top image is supposed to be a cycling selection of images. However, it’s stuck on the first image, and nothing happens when you click it. What could be causing this?

[portfolio_slideshow id=29 include="330,331"]

Thanks! Really grateful for any help.
