Lightbox Gallery Slideshow Block

Hi there!

I am currently moving a client from 7.0 to 7.1 and there is one thing from his 7.0 site that he really wants on the 7.1 site - but I'm not sure how to go about getting him that, haha.

In his current site on the portfolio page, https://www.hka.nyc/lacma , he is able to lightbox the scrolling gallery. Is there anyway to do this in the new 7.1 site? The url is https://hkanyc.squarespace.com and the password is hkanyc

Thanks!
