After the image loads, I want to remove it.  This does NOT work:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Demo</title>
<style type="text/css">
img {
width: 100px;
}
</style>
<script type="text/javascript" src="https://code.jquery.com/jquery-3.1.0.js"></script>
<script type="text/javascript">

$(document).ready(function() {

    var imgI=0;
    $('.showImage img').each(function() {
        var tmpImg = new Image() ;
        tmpImg.onload = function(){

          $(this).remove();

         if( imgI++ === ($('.showImage img').length-1) ) {
          alert('all images loaded!');
         }
        }
        tmpImg.src = $(this).attr('src');
    }) ;
}) ;

</script>

</head>
<body>

 <div class="showImage"><img src="http://www.space.com/images/i/000/056/377/original/fullmoonmultiple.JPG?interpolation=lanczos-none&fit=inside%7C660:*?z2z2322z" alt=""/></div>
 <div class="showImage"><img src="https://upload.wikimedia.org/wikipedia/commons/e/e1/FullMoon2010.jpg?z3z32z22" alt=""/></div>
 <div class="showImage"><img src="https://upload.wikimedia.org/wikipedia/commons/9/9a/Howling_at_the_Moon_in_Mississauga.jpg?3z23z2z" alt=""/></div>

</body>
</html>

Why not doing just this?
$(document).ready(function() {
    $('.showImage img').each(function() {
        var tmpImg = new Image() ;
        tmpImg.src = $(this).attr('src');
        $(this).remove();
    }) ;
}) ;

Or this?
$(document).ready(function() {

    var imgI=0;
    $('.showImage img').each(function() {
      var $this = $(this);
        var tmpImg = new Image() ;
        tmpImg.onload = function(){
         if( imgI++ === ($('.showImage img').length-1) ) {
          alert('all images loaded!');
         }
         $this.remove();
        };
        tmpImg.src = $(this).attr('src');
    }) ;
}) ;

You can do it like this
  $('.showImage img').on('load', function() {
    $(this).remove();
  });

Not sure what you are doing with

tmpImg.src = $(this).attr('src');

Where are you using tmpImg ? Only the last image loaded will actually have a value but you won't be able to access it because tmpImg is declared locally within the event handler?

greetings  skij , , ,  You show JS code that is suppose to eliminate Images <img> as soon as they load into the page, , I do not see this as an effective use of the page structure? ? If you do not want or need these images then do not place the all of <img> into the page. You are trying to get all of the <img> web locations into a newly created "tmpImg"

But I do NOT understand what your code efforts are trying to accomplish? ? ? You seem to need the images (as new images with the identical src ) stored to be used later for something else?

Can you tell us what you are trying to do? And what problem you are trying to FIX with the code block you show, and what result you need (what the new images) to happen, to get the page as you need it? ?
