title: How to return posts AND woo commerce products to same array?
body: <p>I have a website which is currently pulling post_thumbnail images from woo commerce products in the 'homepage-carousel' product category:</p>
  
  <pre><code>$args = array( 'post_type' =&gt; 'product', 'posts_per_page' =&gt; '5', 'product_cat' =&gt; 'homepage-carousel' );
  $loop = new WP_Query( $args );
  while ( $loop-&gt;have_posts() ) : $loop-&gt;the_post();
  </code></pre>
  
  <p>I want to also be able to pull in <code>post_thumbnail</code> images from regular posts in the <code>homepage-carousel</code> category.</p>
  
  <p>How to add both types of post to the <code>$args</code> array?</p>
