Images on products do not show on Product Page

For some reason, some product images do not show up on the single product page for users who are not signed in. The images show up fine once the user signs in. Any help will be most appreciated.

Here is a link to my site: http://www.officialmarkrobertschristmas.com/index.php/product/fashion-pumpkin/

Hello there,

Could you please try to apply the following CSS code through the Simple Custom CSS plugin or child theme’s style.css?

.product.has-default-attributes.has-children > .images {
    opacity: 1;
}

Let me know how it goes.

Regards,
Kharis

PERFECT! … thank you Kharis for the solution, I am truly grateful.
