Callback for shutter effect in Nextgen Gallery

Hello guys, I hope you can help me with this.

I’m having problems with the image layover effect in Nextgen gallery when I scroll down to load new posts.

I am using the shutter effect in Nextgen gallery and everything works except this effext.
I am guessing that I need to enter a callback code for this effect to load but I am not sure what to write here.

My website if you want to have a look, scroll down to the next set of posts and click on an image and you will end up on a new page instead of getting the image popup effect.

Dp anyone know the calback code to write for this script?

Best regards
Victor Eklund
