title: grails 3 load image external folder
body: <p>I would like to load images from an external folder of the same server were is deployed the grails app. Let say in linux - user home.</p>
  
  <p>I've found many articles on the web but without success.</p>
  
  <p>My <code>.gsp</code> code is attempts:</p>
  
  <pre><code>&lt;asset:image src="libs/test/1.jpg"  alt=""/&gt;
  &lt;asset:image src="images/2.jpg"  alt=""/&gt;
  &lt;img src="${asset.assetPath(src: '13123.jpg')}" /&gt;
  &lt;img src="\home\user\img\Desert.jpg" /&gt;
  </code></pre>
  
  <p>I need something like:</p>
  
  <pre><code>&lt;img src="${userhome}/image.jpg" /&gt;
  </code></pre>
  
  <p>where userhome is a predifined folder.</p>
  
  <p>And another question using asset pipeline plugin I get this error:</p>
  
  <pre><code>Byte array resource [resource loaded from byte array] cannot be resolved to URL
  </code></pre>
