Product Thumbnails

Hi

I have read through the forums and ended more confused! I want to set the thumbnail images on the products listing page to be smaller. I tried this assuming that it had been set in the functions.php. I applied the following to a child theme functions.php:

add_theme_support( 'woocommerce', array(
    'thumbnail_image_width'         => 200,
    'gallery_thumbnail_image_width' => 100,
    'single_image_width'            => 500,
) );

I then ran regenerate thumbnails plugin but it didn’t change the size. I then added this to the functions.php

add_filter( 'woocommerce_gallery_thumbnail_size', 'custom_woocommerce_gallery_thumbnail_size' );

function custom_woocommerce_gallery_thumbnail_size() {
return 'thumbnail';
}

I am still not resizing the thumbnail width though.

What am I doing wrong please?

Thanks

Rich
