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>

Solution 3:

I would just use get_the_post_thumbnail_url() instead of get_the_post_thumbnail()

<img src="<?php echo get_the_post_thumbnail_url($loop->post->ID); ?>" class="img-responsive" alt=""/>

Solution 4:

In WC 3.0+ versions the image can get by below code.

$image_url = wp_get_attachment_image_src( get_post_thumbnail_id( $item->get_product_id() ), 'single-post-thumbnail' );
echo $image_url[0]
