Turn img to a background-image of it's parent div. Great for accessing the proportional cropping of bgs while still droppin some meaningful markup.

img to background-image

//Parent div
$('.js-tobg').each(function() {
  
  //Hunt down img in parent div and snag its src
  var imageUrl = $(this).find('img').attr('src');
  
  //Now add inline style with backgroud-image to div
  $(this).css('background-image', 'url(' + imageUrl + ')');
  
  //Maybe cover the badboy?
  $(this).css('background-size', 'cover');
  
  //Visually hide the img tag if you want the div to maintain aspect ratio
  $(this).children("img").css("visibility", "hidden");
});
