When the TableEditor is producing and/or controlling the display the Graphic Image must be

that image. The image must be linked to the Attribution URL so as to access that page
when clicked. If the user interface includes a prominent "about" display which includes
factual prominent attribution in a form similar to that in the "about" display included
with the Original Code, including Socialtext copyright notices and URLs, then the image
need not be linked to the Attribution URL but the "tool-tip" is still required.
