product image size

Hi there,

Sorry for my dummy question, but I don’t undertand how the image are resized for the single product image.
My client send me very big images like that :
https://ibb.co/HTP1JR5
Size 2200*5000 pixels

I resized them with photoshop 300*600

I tried by code :
add_filter( ‘woocommerce_get_image_size_single’, ‘ci_theme_override_woocommerce_image_size_single’ );

function ci_theme_override_woocommerce_image_size_single( $size ) {
// Single product image: square
return array(
‘width’ => 300,
‘height’ => 600,
‘crop’ => 1,
);
}
In this case of course, my image is cropped so it’s kind a zoom in the midlle of the image.

I want to display the whole image but in a smaller size in the product page. I don’t know if I’m very clear in my explanation.

Maybe it’s something to do in photoshop for resizing ???

Thanks for your help.

Best regards.

Catherine.
