Dynamic style settings, images missing

Hey! I’m trying to set up the product page that will display 3 images (side, front,back of each product) after creating 3 divs and place a image in each one, I’m trying to set the product images as viarables in the dynamic setting style but I can’t find the 2nd image and the 3rd. Anyone knows how to solve this?

Here is my site Read-Only: LINK

Make sure your Products CMS has fields for 2nd Image and 3rd Image. It looks like right now the only fields it has is Media and Main Image. You can edit the Products CMS by clicking the Shopping Basket icon in the far left, then hover over Products and clicking the settings gear. Finally you can add new fields with the Add New Field button.
