title: How do I add a color overlay on wordpress images/homepage - or an opacity drop? (before-hover)
body: <p>How do I add an color overlay or maybe an opacity drop the the images on a wordpress homepage - they have a color overlay on hover - but I want them to be darker in the picture color, as I am trying to go with a dark theme.</p>
  
  <p>As you can see on the left one - I have toned it down a little in photoshop, whereas the right image is how they normally look.</p>
  
  <p>Is there a way to do this rather then possibly toning down every image via photoshop before I upload?</p>
