       Enable glow and set color and radius:
           $("#testimg").glow({ radius: "20", color:"green"});
       Disable glow:

$("#testimg").glow({ radius: "20", color:"green", disable:true });

       or
           $("#testimg").glow({ disable:true });

  Version 1.0

   Tested on:
   IPad (IOS 6 required), Chrome 18.0, Firefox 16.0.1, IE 9 (Lower versions should work by Microsoft's browser specifications)
   With jQuery 1.7.2

   Version 1.1

        Added blink feature to blink over one second.
        Example:
       $("#testimg").glow({ radius: "20", color:"green", disable:true, blink:true });

   Version 1.2

        Added configurable blink timegap feature
        Example:
       $("#testimg").glow({ radius: "20", color:"green", disable:true, blink:true, timegap:2000 });
