How to enable Modern/Gallery/Lightbox layout for property images in property details page?

Since WPL2.7.0 we added a new layout for gallery activity named "pshow_modern". It has a lightbox slider in addition to the normal slider. So, when someone clicks on any image on the property details page, he/she will see a lightbox showing actual images (Normally bigger size) using a slider. For enabling this layout navigate to WPL->Activity Manager and search for "listing_gallery". Please check the following figures.
