Body: <p>I'm using Adobe After Effects. I have a composition with several layers. One layer consists of an image which is shown for around 20s. At time point 10s I would like to bring the image to the foreground (relative to the other layers) and at time point 15s I would like to move it again to the background.</p>
  
  <p>How can I achieve this?</p>
