Here are the results from WebKit, according to Accessibility Inspector in Mac
OS X 10.5:

<img> has alt="<the empty string>" its role=AXWebarea, its
AXRoleDescription=HTML content
<img> has no alt its  role=AXimage, its AXRoleDescription=Image
<img> has alt="<space or text>" its role=AXimage, AXRoleDescription=Image

So Webkit looks consequently at the @alt: if the @alt contains if only space
character, then the <img> is considered an image. But if the content is the
empty string, then the users doesn't get any info whatsoever about the presence
of the iamge - it is conflated with the page. 

Steve, when you said alt="text", did you include alt="<space>" ?
