Technique A.1.1 
<http://www.w3.org/TR/1998/WD-WAI-PAGEAUTH-19980918#A1.1%22> [Priority 
1]: Provide alternative text for all images, including invisible or 
transparent images.

*If authors cannot use style sheets and must use invisible or 
transparent images* to lay out images on the page, they must supply 
"null" (alt="") or "white space" (alt=" ") alt-text, whichever the 
context requires.
