Image Carousel on Advanced Posts Module

Anyone have any success adding an advanced custom field of a gallery image to the posts module? I’d like to make the Featured Post Image a gallery of photos with a carousel to cycle through them. When I try customizing the layout, I can’t add an image gallery by inserting an advanced custom field. It will only allow me to add an image.

Here’s the page if anyone can help me figure out how to make that happen. Homeset Destinations - My 5 Homes
