How to add project gallery

Hi Skandha, I'd like to include a project gallery on my website, both on the homepage - visible when scrolling down - and as a separate page in the main menu. It should look similar to the gallery in your demo https://catchthemes.com/demo/bold-photography-pro/, where it is shown as 'Latest release'. I have downloaded the theme content and am working from that. I can't get it right myself. I probably changed some settings or deleted some elements: https://spotonlichtontwerp.nl/staging/ Please tell me how to do this. All the best, Paulo
