Getting image width and height with jquery

Question

I have a very simple code, which annoyingly was working and for the life of me I can not see why it is now failing:

function imageSize(img){
  var theImage =         


        

Answer 1

The image may not have loaded yet. So, try (untested):

function imageSize(img){
  var theImage = new Image();
  $(theImage).load(function() {
    var imgwidth = this.width;
    var imgheight = this.height;

    alert(imgwidth+'-'+imgheight);
  });
  theImage.src = img.attr('src');
}
