Enfold and Woocommerce – single product pages

Hi! :)

I’ve been looking everywhere for a solution to this, and I cant find it. What I want to do is simply to change the way a single product page looks – specifically, the size of the main image (it needs to be big – I’ll be selling art and the picture needs to be full size or close), and the placement of the product info (preferably below the large main image).

And I want to do it with coding. I have no knowledge of coding what so ever.

I’ve tried changing pixel size under woocommerce – settings – products – display. No result, even when I regenerate thumbnails.
I’ve looked all over for a plug-in that does it (preferably free, but not necessary), can’t find any.
I’ve googled ad searched YT for hours, no solution.

Any help would be highly appreciated! :)
