title: TYPO3: get path out of file reference in Extbase
body: <p>i've created a Custom Content Element with Fluid and Extbase (TYPO3 6.1), in which you can define a picture. 
  In the picture-settings i can set a img-link, which is targetting a file.</p>
  
  <p>In my Controller i can access this data with</p>
  
  <pre><code>$this-&gt;configurationManager-&gt;getContentObject();
  </code></pre>
  
  <p>But i just get a file-reference for this setting and no path. like this:</p>
  
  <pre><code>file:1206
  </code></pre>
  
  <p>I've googled a lot and i didn't find a solution to access the path. Has anybody a solution or knows maybe a function in the configurationmanager or something else? I've spend hours on this problem...</p>
  
  <p>Thanks a lot!</p>
