Vanilla 2

I cannot get prettyphoto to work on my blogger website. http://www.grosgrainfab.com

I included the jQuery library, prettyPhoto javascript and the prettyPhoto CSS in the head of my page.

Then I included the initializing code in the body.

Then on my main page I added this link at the top of my left sidebar:
Instagram


And when I click on that link it doesn't open a lightbox. It just opens a new window to that link.

Please help.
