title: What table holds the information for the main image in Magento
body: <p>Which database table holds the information on what image is supposed to be the <strong>main</strong> image of a product in Magento?</p>
  
  <p>I looked at </p>
  
  <ul>
  <li>catalog_product_entity_media_gallery</li>
  <li>and catalog_product_entity_varchar</li>
  </ul>
  
  <p>But don't see how one image is flagged as the main (Base) image. </p>
