Reduce the product image size for mobile view only

I like the desktop view (two-column structure) but I want to reduce the image size for mobile view only to make my product detailed information like the title, style, “Add to cart” button visible at the first sight when customers get into the product page. I was trying to edit code but I found that this section has lots of css involved as it is box-to-box-to box structure. Hence, I am looking for an easy way to adjust the image size and make the product information upward and visible.


(desktop view)


(too big image)

(product info)
