title: Adding Album Art using python in mp3 metadata
body: <p>The code below doesnt seem to update the artwork of the mp3 file.</p>
  
  <p><strong>Code:-</strong></p>
  
  <pre><code>#Editing the MetaData
  tag = eyeD3.Tag()
  print tag.link('location') //Returns 1
  tag.setVersion([2,3,0])
  print tag.addImage(0x08,'artwork.jpg') //Return None (Its sure that file is present)
  print tag.update()  //Returns 1
  </code></pre>
  
  <p>The values returned by the function are correct but then also the metadata is not getting updated. </p>
