Grid Overlay, How do I turn off individual pages for each picture.

Hello! I love the grid overlay in portfolios, but I do not want each picture to be clickable and have its own separate page. I want to keep the hover/overlay. 

What code should I use and where do I insert that code? 

Thank you!

         $('a.grid-item').removeAttr('href');
});
