The problem with product photos

[kszyhoo11]

I have a problem with the product photos on my website. I use virtuemart version 2.0.24c and I get an error:
"Uncaught TypeError: Object function () {b.open.apply (this, arguments)} has no method 'init'."
What could be the problem? Where is error?
Sample product page: http://studio-deco.pl/sklep/wizytowki/wizytowki-standardowe-350-g-jednostronne-100-szt-detail
Why can not I normally view product images
Help please ...
