title: Highlight parts of an image on mouseover
body: <p>I want to create a page which essentially has a black and white photograph of, say, 5 people. Now, on hover over each person, I want that person to light up and a dialog of information to be displayed next to it.</p>
  
  <p>Can anyone please tell me how to go about doing this?</p>
  
  <p>Thanks in advance. :)</p>
