Even cooler:
1. Using Firefox, go to http://www.cssquirrel.com/comic/
2. Point at the comic strip, and bring up the contextual menu.
(On the mac, Control-Click on the image)
3. Select the Properties in the contextual menu that popped up -
as a result you get a dialog window listing "Image properties".
At the bottom of the "Image properties" list there is the label
"Description" which contains the longdesc URI.
But where are the traces of the aria-describedby? It ain't there.
Just remove the longdesc attribute, and the description field is
gone. Aria-describedby isn't a property of the image.
