title: Remove featured image from showing on product display page
body: <p>I am using wooCommerce and Wordpress.
  When you set the featured image for a woocommerce product, it shows up as the first/main image in the gallery on the product details page. I don't want this. I simply want to hide/remove the featured image entirely from the product details page. I want the featured image to only show up in the product category page but not on a single product detail page. 
  I tried removing the image with the code 
  <code>remove_action( 'woocommerce_before_single_product_summary', 'woocommerce_show_product_images', 20 );</code>
  in theme functions file.
  Still unable to see desired results.</p>
  
  <p>I'm using the theme <a href="http://elementsmart.com/product/rock-sunglasses-2/" rel="nofollow">room09</a>.</p>
  
  <p>I want to hide this vertical image (have set it featured image) from showing on this page only.</p>
  
  <pre><code>&lt;div class="images"&gt;
  
  &lt;?php
      if ( has_post_thumbnail() ) {
  
          $image              = get_the_post_thumbnail( $post-&gt;ID, apply_filters( 'single_product_large_thumbnail_size', 'shop_single' ) );
          $image_title        = esc_attr( get_the_title( get_post_thumbnail_id() ) );
          $image_link         = wp_get_attachment_url( get_post_thumbnail_id() );
          $attachment_count   = count( get_children( array( 'post_parent' =&gt; $post-&gt;ID, 'post_mime_type' =&gt; 'image', 'post_type' =&gt; 'attachment' ) ) );
  
          if ( $attachment_count != 1 ) {
              $gallery = '[product-gallery]';
          } else {
              $gallery = '';
          }
  
          echo apply_filters( 'woocommerce_single_product_image_html', sprintf( '&lt;a href="%s" itemprop="image" class="woocommerce-main-image zoom" title="%s"  rel="prettyPhoto' . $gallery . '"&gt;%s&lt;/a&gt;', $image_link, $image_title, $image ), $post-&gt;ID );
  
      } else {
  
          echo apply_filters( 'woocommerce_single_product_image_html', sprintf( '&lt;img src="%s" alt="Placeholder" /&gt;', woocommerce_placeholder_img_src() ), $post-&gt;ID );
  
      }
  ?&gt;
  
  &lt;?php do_action( 'woocommerce_product_thumbnails' ); ?&gt;
  
  &lt;/div&gt;
