Hello There,
Thanks for updating in!
I have checked your site and your WooCommerce image dimension settings. You have this:
It is expected that on in your shop and product archives, you will have 250x275 pixels. When you are in the big screen, most likely the image will blow up to a bigger size because of the default styling. To resolve this and make sure that the image is exactly the same as the size in the settings, please add the following CSS code in the X > Launch > Theme Options > Global CSS (http://prntscr.com/evui3r)
.woocommerce li.product .entry-featured img {
min-width: 100px;
max-width: 100%;
width: auto;
}
The single product page has the WooCommerce Product Slider and Gallery Zoom. If you want to get rid of this and just display the old and simple product image display, please add the following code in your child theme’s functions.php file
// Remove product gallery slider and gallery zoom
// =============================================================================
add_action( 'after_setup_theme', 'remove_woo_three_support', 11 );
function remove_woo_three_support() {
remove_theme_support( 'wc-product-gallery-zoom' );
remove_theme_support( 'wc-product-gallery-slider' );
}
// =============================================================================
Hope this helps. Please let us know how it goes.
