title: Hide thumbnail for specific product categories in WooCommerce cart
body: <p>I'm trying to hide the image in the WooCommerce Cart for certain categories. I found that adding this code removes all thumbnails from the Cart:</p>
  <pre class="lang-php prettyprint-override"><code>add_filter( 'woocommerce_cart_item_thumbnail', '__return_false' );
  </code></pre>
  <p>I'm trying (and failing), to only remove this for certain categories, using the following code.</p>
  <pre class="lang-php prettyprint-override"><code>function WooCartImage($woocommerce_cart_item_thumbnail) {
  if ( is_product_category(63) ) {
      $woocommerce_cart_item_thumbnail = '__return_false';
  }
  
  return $woocommerce_cart_item_thumbnail;
  }
  add_filter( 'woocommerce_cart_item_thumbnail', 'WooCartImage' );
  </code></pre>
  <p>I'm not sure where I'm going wrong with this and if anyone has a hint, that would be great!</p>
