Product image Solution

[SliderFlash]

Image error in the preview image, the image in the preview is displayed too small than in the settings, see demo Prestashop.

SOLUTION:

themes/classic/templates/catalog/_partials/product-images-modal.tpl:

in line 33, delete img - fluid, save and upload again.

 <figure>
          {if $product.default_image}
            <img
              class="js-modal-product-cover product-cover-modal img-fluid"

after that the images will be displayed in correct size as in the setting.

The bug seems to be fixed in the current PrestaShop version, in the current version is displayed in correct size.
