How to showcase selected custom product options as large images?

Hi,

I am using globo product options PRO on my website for the product options to make them customisable. I can’t seem to get my head around how when someone chooses an image from the selection it shows in the product image space. I want them to be able to choose a background but be able to see it large so they can see the details and what it will actually look like. Any help is appreciated, my website link is https://toonyourcar.myshopify.com/collections/designs/products/car-illustration

Thanks everyone!

I’m having the exact same problem and I see no one responded to your question a year ago. Wasting time trying to figure it out now.
