title: Use different thumbnails size for an specific "archive page" of a category in woocommerce
body: <p>I have a great store made in woocommerce but thumbnails in archive pages for 2 of my 9 different categories are cropped too much since my thumbnails are vertical (700x900), this images for this 2 categories must be in horizontal, using 500x300 so the cropping doesn't affect the picture too much, is this possible?</p>
  
  <p>For example I want to keep all categories to default thumbnails (700x900) but I need category ID 23 and 27 to use 500x300 thumbnails.</p>
  
  <p>I found this code, but I cant make it work for woocommerce:</p>
  
  <pre><code>  if (in_category( '23' )) {
      // different size for one category
      set_post_thumbnail_size( 500, 300, true ); 
  } else {
      // default size
      set_post_thumbnail_size( 700, 900, true ); 
  }
  </code></pre>
  
  <p>I already added the custom image size and regenerated my thumbnails.</p>
  
  <p>I will appreciate any help or clues how to solve this.</p>
