My Answer:
To add a custom image field to the WooCommerce product creation panel, you can use the following code:

php
// Display Fields
add_action('woocommerce_product_options_general_product_data', 'woocommerce_product_custom_fields');
// Save Fields
add_action('woocommerce_process_product_meta', 'woocommerce_product_custom_fields_save');

function woocommerce_product_custom_fields()
{
global $woocommerce, $post;
echo '

';
woocommerce_wp_text_input(
array(
'id' => '_custom_product_text_field',
'placeholder' => 'Custom Product Text Field',
'label' => __('Custom Product Text Field', 'woocommerce'),
'desc_tip' => 'true'
)
);

echo '

' . __('Custom Product Image Field', 'woocommerce') . '

Upload Image

';

echo '

';
}

function woocommerce_product_custom_fields_save($post_id)
{
// Custom Product Text Field
$woocommerce_custom_product_text_field = $_POST['_custom_product_text_field'];
if (!empty($woocommerce_custom_product_text_field))
update_post_meta($post_id, '_custom_product_text_field', esc_attr($woocommerce_custom_product_text_field));

// Custom Product Image Field
$woocommerce_custom_product_image_field = $_POST['_custom_product_image_field'];
if (!empty($woocommerce_custom_product_image_field))
update_post_meta($post_id, '_custom_product_image_field', esc_attr($woocommerce_custom_product_image_field));
}


This code will add a custom image field to the WooCommerce product creation panel. The field will allow users to upload an image for the product. The image URL will be saved as post meta data for the product.
