cls shifting after installing the plugin

Hi ,

after using the paid plugin (videos and pics) on our website google page insigts reports massive cls shifting on our page .

Our score dropped from 100% (mobile ) to 70.

I see below that someone had the same issues.. can you advise us how to use the for our website ? My main question is how to chose the with and height depending on the page.

@media only screen and (max-width: 768px) {
  /* For mobile phones: */
  .images.nickx_product_images_with_video{
    min-width: 370px;
    min-height: 470px;
  }
}

The page I need help with: [log in to see the link]
