Dynamic image rotation is most commonly used # for pictures taken in portrait mode by turning a camera vertical, so # that the image is lot lying on it's side. The un-rotated width is # usually more than the un-rotated height. So, when the TD uses the # un-rotated height for its calcuation, it gets a smaller value than the # rotated heights, so it positions the IMG too close to the top of the # TD, and overflows the TD, perhaps even being clipped by the top of the # browser window. # echo " " echo " " echo " " echo " " echo " " echo " " echo " " echo " " echo "
