Show two product images on the product page for PS 1.7

[Augen2203]

I would like to know if you can help me to get two images for each product in product-list.tpl, I have seen several responses about this subject associated with PS 1.6, but obviously, they are not useful for 1.7, Maybe I'm wrong. If you come across this, I will be very grateful for your help!
