I am setting background image on div:

div.css('background-image', 'url("' + imageSrc+ '")')

But I also need to get image dimensions, so I need to load this image again:

var image = new Image();
image.src = imageSrc;

image.onload = function () {
var width = image.width,
  height = image.height;

};

Does this mean this image is loading twice and its not cached as well? Is there a different way to prevent this?
