Javascript - Get Image height

I was searching a solution to get height and width of an image using JavaScript. I found many, but all those solutions only worked when the image was present in browser cache.

Finally I found a solution to get the image height and width even if the image does not exist in the browser cache:

<script type="text/javascript">

  var imgHeight;
  var imgWidth;

  function findHHandWW() {
    imgHeight = this.height;
    imgWidth = this.width;
    return true;
  }

  function showImage(imgPath) {
    var myImage = new Image();
    myImage.name = imgPath;
    myImage.onload = findHHandWW;
    myImage.src = imgPath;
  }
</script>

Thanks,

Try this:

var curHeight;
var curWidth;

function getImgSize(imgSrc)
{
var newImg = new Image();
newImg.src = imgSrc;
curHeight = newImg.height;
curWidth = newImg.width;

}

You can use img.naturalWidth and img.naturalHeight to get real dimension of image in pixels
