title: How to reduce compression rate on the cover image?
body: <p>I don't know if this is the correct place to be asking this, but I don't know where else to ask it.</p>
  
  <p>When we upload an image as cover photo for our facebook page, the quality is dreadful. This only happens when there are illustrations in it. When it's a full picture, everything is perfect.</p>
  
  <p>So my question is, is there anything you can do to reduce the compression rate of facebook, or is it all upto them? For instance, are there any saving options in photoshop which are beneficial for the quality (on facebook)?</p>
