Glowing image with jQuery/Javascript

Question

I have two images. One that is normal, and another that is more colourised. I want to have this image displaying on top of the other and having a "glowing" effect where it switches between transparent and opaque every second or so. I also need to stop this effect when the user presses a particular button. How would I go about doing this with jQuery or Javascript?

I'm not sure if I can use CSS, since the animation must be stopped in response to a button. — danieljmt, Jun 26 '12 at 17:59
setup a demo fiddle. (http://jsbin.com) Show us how your HTML / CSS looks like. — Roko C. Buljan, Jun 26 '12 at 18:00
@DanielMarshall you can always remove the animation from css when button clicked — Huangism, Jun 26 '12 at 18:00

jsBin demo

html:

<button id="stop">STOP IT!</button>

<div class="images">
     <img src="img1.jpg" />
     <img src="img2.jpg" class="glowed"/>
</div>

jquery:

var playing = true;

function loop(){
  if(playing){
    $('.images img:eq(1)').fadeIn(700, function(){
      $(this).fadeOut(700,loop);
    });
  }
}

loop(); // start loop


$('#stop').click(function(){
  playing=0;
});

Just position the two images absolute:

  .images img{
    position:absolute;
  }

  .glowed{
    box-shadow: 0px 0px 30px 2px #cf5
  }

I used css3 box shadow, but you could use a glowed .png image instead.
