img without height or width selected returns 0px in IE

I found that problem, in IE if img have width or height empty return 0px, so the image isn't displayed correctly.
An example if i set-up 200px as width and empty or 0 in height (I would have height depending aspect ratio of original image embedded) tag with width="200" height="" ... that returns 0 px height in IE!

Here is the patch that output only width or height if that aren't empty. :)
Please correct and include that patch in next version. thanks
