Hi,

Currently, we don't have option to disable lightbox. I will add this on our to-do list for one of the future updates.

The only way to do this now, is to edit the file wp-content/themes/recycle/js/functions.js directly.

First I suggest you make a copy of this file for backup (just in case).

Then search and delete this part of js code:

 $('a[href]').filter(function() {
 return /(\.jpg|\.jpeg|\.gif|\.png)/i.test( $(this).attr('href'));
 }).addClass("swipebox");

It should be around line 1067. 

Kind regards,
Andrej
