Remove lightbox have link to page instead

Hi there !

I know this topic has been approched here, but I still don’t figure it out.

I’m using free version of this great plugin. WordPress 4.0.

I tried to modify elements in php files like explained here, but I don’t find the proper elements.

Where could I modify the code to remove the lightbox ang to link tumbnails to pages ?

Thanks a lot !
