note 51584 added to function.getimagesize

I found this marvelous little function for getting image dimensions. I thought it was going to be the answer to a dilemma I was attemting to solve with my automated web site creator. Alas, when using PHP and JavaScript in HTML pages and opening popUp windows there is way to much hassle trying to share the variable all around. If somebody could help me by explaining how this information is extracted from an image file I'll create my own function that will be easily usable in JavaScript.
