Do you mean the related products in the individual product page?
If so then you can filter how many related products you want to make appear in the page.
Are you using any woocommerce associated plugin? You just need to go through the settings and then you can filter the sorting.
Thanks for this but the problem is to display all the photos of the product inside the product page not the number of the products per page in the shop.
For example this product https://shoewarehouse3.com/shop/product/124/ has 9 photos from different angles but when the page loads it shows only 4 photos and hides the rest.
It must be the plugin issue if you have used any. Please check the settings if you have.
What you can simply do is go to Dashboard>>Products and set additional variation image gallery as follows; Additional Variation images
