Bruce, We are trying to stay in sync with the WAI guidelines so to follow http://www.w3.org/TR/WAI-WEBCONTENT-TECHS/#spacer-images: ALT=" " (1 or more spaces) is NOT allowed. ALT="" (NULL) IS allowed for spacer images. The WAI techniques also suggest that the ALT text for spacer images be "spacer". I like this better than the NULL text. I propose that I modify technique 1.1.A so that NULL ALT text is suspicious and if found, the user is prompted with: "ALT text for this image is NULL. If the image is used for spacing use 'spacer' as the ALT text." >I disagree (rather vigorously) with the suggested text for bullets and >horizontal rules. ALT (alternate) should replace function and not form. > >* 2. If the width of the image and the height of the image are both less >than 20 pixels, suggested text should be "bullet". > >Suggested text should be "-" or "." or "*" or "+"! > >* 3. If the height of the image is less than 20 pixels and the width of the >image is greater than 150 pixels, suggested text should be "horizontal >rule". > >Suggested text should be "----"! > That sounds fine to me. It makes it more language independant. >We could recommend that authors include the "TITLE" attribute (which >should, if included, be "bullet" or "horizontal rule"). It is not clear to >me that any browsers support the use of TITLE for images though... > This may be added complexity for something that is not used. Can we drop this recomendation?
