How to remove photo gallery?

Hey Fellas…

How can I remove this photo gallery box: https://adidas-talk.com/photos/adidas-originals-jeremy-scott-2009-fallwinter-lookbook (the black box) I want the thumbnails to enlarge when you click on them rather than to load into that black box and click the image in the blackbox to enlarge.

Here’s the single_Photo.php template: https://www.filedropper.com/singlephotos

Maybe that will be of some help.. please let me know as I want to have replace it with this plugin: https://www.shadowbox-js.com

Thanks!
