Question about features in the premium version before upgrading

Hi,
I am currently using the free version of your plugin on my pro website.
There is a feature that I need and I don’t know if it is possible with the premium version, and I don’t want to upgrade unless I am sure of being able to use it right. Here is what I’d need :

On my product page, I have a scroll-down menu with a list of items to choose (these are themes for birthday parties products). When my customer choose the theme of their choice, I would like the image of that theme to appear just below.
For now all I can do is change the product image on my website theme by managing it it the variation section of my product page settings. But I don’t want to do it that way.

Here is an example of what I would like to do : https://www.ohmyconfetti.fr/produit/badges-personnalises-x10/

Can you tell me if it is possible and where should I set this ?
Is there any way I could test the premium version to see if the feature that I need is available?
Thank you for your answer,

Have a nice day
Justine Biaut
