title: A glow around a circular image with CSS on hover
body: <p>I want there to be a "glow" effect around a circular image I have (it appears as a circle, but it really is a square image with transparent pixels to make it appear as a circle).  </p>
  
  <p>Is there an easy and efficient way to do this with CSS?  I have tried box shadow, but it doesn't seem to be working correctly.</p>
