How to get image size (height & width) using JavaScript?

Question

Are there any JavaScript or jQuery APIs or methods to get the dimensions of an image on the page?

Answer 1

The thing all other have forgot is that you cant check image size before it loads. When the author checks all of posted methods it will work probably only on localhost. Since jQuery could be used here, remember that 'ready' event is fired before images are loaded. $('#xxx').width() and .height() should be fired in onload event or later.
