Not getting Masonry Gallery Layout..!!!

Dear Virtue Support Team,

I am using Lightbox Slider Pro plugin for displaying my images on the individual pages. I have the option of using them either in 2,3,4 or 6 columns. I am using the option to display images in 3 columns in individual pages.

I was getting the perfect masonry layout for all my galleries but I believe after the update of the theme I have lost that perfection.

Can you please help me get masonry layout display for my images? Link to one such page on my website is :

Please help.

Thanks and Regards
