Hi Maybellyne,
thank you for your message!
Exactly, “projects” is a special post type, which is pre-programmed by the purchased theme (Prague).
The large image at the top of the projects-pages is the featured image. The smaller images below (front view and side view of the glasses) are included in a gallery element, which is part of the template.
Does that help you?
Best, Lis
Thank you so much for your quick help!
If it isn’t affecting the end-users, I’m happy! 🙂
