I don't remember the size of this original image, so I am just going to play.
In fact, to make an image smaller or larger, you should keep the height and
width the same proportions that they were originally. Also note that it is
better to resize the image before you include it so you do not have to
use width and height.
Now I am going to warp the height which seems to work well with the same
height and width for this image.
