pictures & movie

Hi,
Is it possible to have a gallery with photos and movie together?

And… can you explain in easy language how to have a movie in a (or that) gallery? I don’t understand this explanation (https://visualportfolio.co/documentation/portfolio-items/video-portfolio-item/).

(the page is still building and so in Private mode. if… I can let you login).

The page I need help with: [log in to see the link]
