"spacer" images so I'd say it makes sense to ignore such small images
anyway. "

While the width and height attributes are 0 and 1, the images does have a
CSS width and height
h2 img{position:absolute;width:700px;height:202px}

More importantly I believe some automated tools get the width and height
from the image file properties rather than the DOM or HTML source code.
Additionally, while in this example the alt is null automated tools must
deal with developers who do not correctly set the alt attribute to null.
