How to get featured image of a product in woocommerce

Question

Please tell me where I am going wrong . Product featured image is not showing up.

   $args = array( 'post_type' => 'product', 'posts_per_page' => 80, 'product_cat' => 'profiler', 'orderby' => 'rand' );

    $loop = new WP_Query( $args );

   while ( $loop->have_posts() ) : $loop->the_post(); global $product; ?>

    <div class="dvThumb col-xs-4 col-sm-3 col-md-3 profiler-select profiler<?php echo the_title(); ?>" data-profile="<?php echo $loop->post->ID; ?>">

    <img src="<?php  get_the_post_thumbnail($loop->post->ID); ?>" data-id="<?php echo $loop->post->ID; ?>">

    <p><?php the_title(); ?></p>

    <span class="price"><?php echo $product->get_price_html(); ?></span>                    
    </div>

I have already added a featured image in back end

Answer 1

I got the solution . I tried this .

<?php $image = wp_get_attachment_image_src( get_post_thumbnail_id( $loop->post->ID ), 'single-post-thumbnail' );?>

    <img src="<?php  echo $image[0]; ?>" data-id="<?php echo $loop->post->ID; ?>">
