Only getting image without prettyPhoto interface

Hi,

We’re using shashin plugin to display google picassa album as in http://www.academyofplay.org/#event-media.
The moment I click the individual photos, it only displays the image and no prettPhoto interface appears and can’t slide through the images.
In chrome, I don’t see any errors and apparently can’t figure why prettyPhoto just stops working.
A sample image link (on the image) is as follows: https://lh3.googleusercontent.com/-50apTMkpWR4/VkQH82cnYlI/AAAAAAAABvM/HuOwagYlk6g/IMG_0837.jpg?imgmax=912.

Appreciate if anyone could point what goes wrong to fix this?
