Images with width/height attributes have "Auto" default size even though they have a width and height

[pmasekito]

Images with a width or height attribute aren't detected properly:

Ex)
<img style="display: block;" border="0" src="link_here" width="290" height="180" />

Hit "Change Size" on image pop up toolbar and it displays "auto" instead of the width or height they have (290x180).

Within "refreshSizePopup" it uses image_object.style.width or image_object.style.height rather than checking for all potential values (perhaps try with image_object.width() ?)

Either way, would love to get this fixed.
