title: Display a custom field image on Visual Composer Custom Grid Template
body: <p>I'm working on a WP site with Visual Composer.</p>
  
  <p>In the homepage I've inserted a "Post Grid" element which load a specific custom post type.</p>
  
  <p>This custom post has multiple custom fields (made with Advanced Custom Fields Plugin): one of these fields is an image.</p>
  
  <p>This Post Grid uses a custom grid to display these custom fields.</p>
  
  <p>When I preview the page, it displays correctly the post thumb (the post featured image), some text custom fields, but the secondary image (created with a custom field) displays only text (in the specific the Array Object or ID of the image).</p>
  
  <p>How can I render the image? Is it possible to insert some code for that custom field (ex. the omg html tag) to avoid the text render?</p>
  
  <p>Thanks in advance,
  Francesco</p>
