Replacing the current zoom gallery for a product card?

Question

css

There is such a gallery with a zoom effect, the problem is that when you open a product, all the pictures are loaded, and they are very large there, but you need only previews to be shown when opening.
Now the gallery is on the site meybag.ru/product/meyninger-6025-rose-red.html
Who knows the gallery better?

Answer 1

phpThumb or imagemagick to help
when clicking - replace src and profit.
