 Replying to [comment:42 rianrietveld]: Rian, I absolutely love what you're
 doing here.
 > Agree that every image need an alt tag, even if it's alt="".
 As I alluded to in ticket #28861, I am as worried about an empty alt
 atribute as I am a bad one.  As I understand it, empty alt attributes will
 cause some screen readers to remove focus from the image, which, in the
 case of the headers for certain themes, is also serving as a link home.
 I don't know if the empty alt attribute over-rides the <a> element, or
 vice versa, when it comes to screen reader technology. And, many of us
 have learned that we should leave an alt attribute empty rather than put
 in descriptions for decorative images--which is why I was considering
 adding the ARIA features to it, so that if the alt attribute is handled
 incorrectly, users would understand that it is a link home.

 Thanks to all for everything that's being done here.
