Variation image sizes in popup

Hi there,

I just purchased the checkout funnel plugin.
In the design if I choose the “add to cart checkbox” template, I see my variation images are very small in the popup, when i click “choose option”.
Anything I can do about that?

Would also like to know if I can change the language in the popup?
I tried with Loco translate, but didn’t work.
