title: Display an image from a file location
body: <p>I would like to show an image from a location in my public directory.  In my model I have created a path for the image but when I call it in the show action it simply displays the string.  </p>
  
  <pre><code>  def img_path
  "&lt;img src='/system/assets/10/original/airplane.jpg'&gt;"
    end
  </code></pre>
  
  <p>Here is the html:</p>
  
  <pre><code>      &lt;td&gt;&amp;lt;img src='/system/assets/10/original/airplane.jpg'&amp;gt;&lt;/td&gt;
  </code></pre>
