simplest way :

<img src="pict.jpg"
  onmousover="alert('width = '+this.width+' height = '+this.height)";>

maybe your code would be better with :

var myWidth= myImage.style&&myImage.style.width? myImage.style.width :
  myImage.width; //attempt to capture width of <img>
var myWidth= myImage.style&&myImage.style.height? myImage.style.height :
  myImage.height; //attempt to capture height of <img>

idea :
If your image didn't get a width or height style, you can't catch it.
