How can I limit image loading on my product page?

Hi All,

I would like to adjust my code such that only the first 4 images are shown (one row) I would also like all of the images besides the first image to be placed below my “add to cart” section on mobile view. Currently, only the second image (showing 3 candles) is doing this correctly. Please let me know if you are able to help and thank you in advance!
