I wanted to create a lightbox effect for images when clicked, so eventually I found this tutorial and followed all the necessary steps to insert it into my page (with a little modification).
The lightbox functions exactly the way I want it to, but the jQuery library used for the lightbox is conflicting with another script and it's messing up the multi-column layout and endless scroll.
This is a mock page with the lightbox effect. Normally, all the posts should be scattered in a lose multi-column fashion and new posts should load with endless scroll.
I tried deleting a bunch of things to see where the conflict was, and these are the two scripts that conflict.
