The wc_get_image() function takes four parameters:

1. $product_id (required) - the ID of the product whose image you want to retrieve.
2. $image_size (optional) - the size of the image you want to retrieve. The default value is 'full'.

4. $placeholder_image (optional) - a boolean value that determines whether to display a placeholder image when the product does not have an image. The default value is true.

Return Value

The wc_get_image() function returns the URL of the image as a string.

Example

<?php
$product_id = 123;
$image_size = 'medium';
$attributes = array(
    'class' => 'product-image',
    'alt' => get_the_title($product_id),
);
$image_url = wc_get_image($product_id, $image_size, $attributes, true);
echo "<img src='{$image_url}' />";
?>

This example retrieves the URL of the medium-sized image for a product with ID 123, adds the product-image class and title attribute to the image tag, and displays the image on the webpage.
