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

You have to wait , till your image will be loaded , and then access to its sizes:

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

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

}
