Woocommerce Product Thumbnail sizing - php

Question

I am trying to get all small medium large and full thumbnail sizes in the SHOP page of woocommerce. I am using the following code in woocommerce.php (duplicate of page.php) to display all products
<?php woocommerce_content(); ?>
Next I have put the following code in functions.php but all in vain
<?php
/**
* Hook in on activation
*/
/**
* Define image sizes
*/
function yourtheme_woocommerce_image_dimensions() {
global $pagenow;
if ( ! isset( $_GET['activated'] ) || $pagenow != 'themes.php' ) {
return;
}
$thumbnail = array(
'thumbnail' , 'medium' , 'large' , 'full'
);
$index = array_rand($sizes);
// Image sizes
// Single product image
update_option( 'shop_thumbnail_image_size', $sizes[$index] ); // Image gallery thumbs
}
add_action( 'after_switch_theme', 'yourtheme_woocommerce_image_dimensions', 1 );
?>
I am new to woocommerce and I wish to achieve a masonry layout with these different thumbnail sizes. Any help would be greatly appreciated.
Thank You in advance.

Try following code:
<?php
/**
* Hook in on activation
*/
/**
* Define image sizes
*/
function yourtheme_woocommerce_image_dimensions() {
global $pagenow;
if ( ! isset( $_GET['activated'] ) || $pagenow != 'themes.php' ) {
return;
}
$thumbnail = array(
'thumbnail' , 'medium' , 'large' , 'full'
);
$index = array_rand($thumbnail);
// Image sizes
// Single product image
update_option( 'shop_thumbnail_image_size', $thumbnail[$index] ); // Image gallery thumbs
}
add_action( 'after_switch_theme', 'yourtheme_woocommerce_image_dimensions', 1 );
?>
