title: Magento custom image attribute. How do I get in frontend?
body: <p>I've added an image attribute with name and label e.g. New Image, new_image.</p>
  
  <p>How do I fetch this from e.g. view.phtml? I thought it would be as simple as </p>
  
  <pre><code>&lt;?php
      echo $this-&gt;helper('catalog/image')-&gt;init($_product, 'new_image')-&gt;resize(150, 150);
  ?&gt;
  </code></pre>
  
  <p>But, this is throwing an error. </p>
  
  <p>Does anybody know the correct way to do this?</p>
  
  <p>Many thanks.</p>
