Get the real width and height of an image with JavaScript? (in Safari/Chrome)

Question

I am creating a jQuery plugin.

How do I get the real image width and height with Javascript in Safari?

The following works with Firefox 3, IE7 and Opera 9:

Answer 1

function getOriginalWidthOfImg(img_element) {
    var t = new Image();
    t.src = (img_element.getAttribute ? img_element.getAttribute("src") : false) || img_element.src;
    return t.width;
}

You don't need to remove style from the image or image dimensions attributes. Just create an element with javascript and get the created object width.
