Image upload not showing on page

Hi there!

I’ve recently been building a new webshop, and I can’t get the image upload to function. I have tested (and use) most of the other options already, it’s just this one function that will not show on the page no matter what.
I do not have the option to click on ‘show on product page’ btw.

Anyone that could help me out? I’d be very thankful!
