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

This works cross browser

var img = new Image();
$(img).bind('load error', function(e)
{
    $.data(img, 'dimensions', { 'width': img.width, 'height': img.height });                    
});
img.src = imgs[i];              

get the dimensions by using

$(this).data('dimensions').width;
$(this).data('dimensions').height;

Cheers!
