Adding div dynamically, but images very slow to load

Question

I'm creating divs dynamically based on ajax callbacks. Each div contains a single png image:

var myDiv = "<div class='myClass' id='divid'>" + 
            "<img id='newDiagDivId' src='images/approved-icon.png'>" + 
            "<div style='display:inline-block;vertical-align:top;'>blah</div>" + 
            "</div>";

...here's how I add it:

$(myDiv).hide().appendTo( divContainer).fadeIn( 100);

The div displays correctly formatted, but the png image takes about 5-10s to show up. It's a tiny image, just 2kb, hosted locally from the app itself. The issue occurs on FF, Chrome, and IE, there's literally no difference in behavior.

The page handles about 2-3 ajax callbacks per second in "rapid fire" fashion, spitting out these divs for each callback, I don't have a slow machine, so I don't suspect the browser falling behind while loading the images.

Is there anything I can do to force the images to load faster or, immediately upon the div being added to the dom?

Ok, so I'm answering my own question yet again...

Decided to preload images in the DOM based on this , works in FF, Chrome, IE!

$(window).load(
      function() { 
          preload(['images/approved-icon.png','images/denied-icon.png'])});

function preload(arrayOfImages) {
    $(arrayOfImages).each(function () {
        $('<img />').attr('src',this).appendTo('body').css('display','none');
    });
}
