gravataresponsive.js

setInterval(function(){
  if(window.devicePixelRatio > 1) {
    jQuery('img.profilePic').each(function(){
      var el=this;
      if(!el.src.contains('gravatar.com')) return;
      el.src = el.src.replace(/\bs=(\d+)/, 
        function(match, px) {
          return "s="+Math.round(window.devicePixelRatio*jQuery(el).innerWidth());
        });
    });
  }
}, 250);
