Exif Orientation leads to wrong scaling

[helmut8080]

Hi,
first I like your script. Very well done!
I have in my project

img {
	image-orientation: from-image;
}

With this enabled images are wrongly scaled when the image needs to be rotated because of the orientation. As I did not find a quick solution to read the exif information I did it quick and dirty change in row 213.

if (Math.round(img.naturalHeight/img.naturalWidth * 100) == Math.round(img.width/img.height * 100)) {
    	that.imgHeight = img.naturalWidth || img.width;
        that.imgWidth = img.naturalHeight || img.height;
    }
    else {
	    that.imgWidth = img.naturalWidth || img.width;
	    that.imgHeight = img.naturalHeight || img.height;
    }

And it works (at least in my cases) Would be great if you have a cleaner solution.
Thanks again.
