title: How to remove ID3 audio tag image (or metadata) from mp3 with ffmpeg
body: <p>FFMPEG is really a great tool. I know it can edit ID3 tags and even remove all tags in a row :</p>
  
  <pre><code>ffmpeg -i tagged.mp3 -map_metadata -1 untagged.mp3
  </code></pre>
  
  <p>But even after that, there's still the cover image. </p>
  
  <p>I don't know how to remove it using ffmpeg. I know there's other soft out there that can do the job - like eyed3 - but what's the point to install it if ffmpeg can do it too, in one line, while encoding the audio ?</p>
