Portfolio Issues

I am trying to create a portfolio page on my current website. The page is not currently live I am still in the process of adding content.
However on the ‘preview page’ only the ‘main image’ from the content list is appearing, whereas there are a few preliminary images I had added to the cms part of the process.
Basically does anyone know how to incorporate those other images (listed as gallery images on cms) to the live site?

What have you already tried:
Struggling to find on the cms or site editor where I can select to add these in.

Additional information:
[Include any other pertinent details or information that might be helpful for people to know when trying to answer your question.]

What did you use to connect the image?

Did you use a single image element by itself?

Did you use a single image element in a repeater?

Did you use a gallery element?

What type of field did you use in your database? Did you use a single image field column? Did you use a single gallery field column? Or did you create a bunch of columns of single image fields for 1 item/row? (Like: image 1, image 2, image 3, etc)

How you organized your database will determine how you link up your elements on the page.
