If you’re using the WooCommerce plugin for WordPress, you may want to change the thumbnail size. The default size is 150 pixels square, but WooCommerce generates its own thumbnail image sizes.
The size name of WooCommerce image size is “woocommerce_thumbnail” and “shop_catalog”. After knowing the names, we can retrieve them from a list of image size names with a global variable called $_wp_additional_image_sizes.
//get all size names with their dimensions global $_wp_additional_image_sizes; //get width and height of woocommerce_thumbnail $woo_image_size = $_wp_additional_image_sizes['woocommerce_thumbnail']['width'].'x'.$_wp_additional_image_sizes['woocommerce_thumbnail']['height'];
