>Secondly you do not need alternate content. I do not know who is >distracted by non animated, relevant, illustrative pictures. People who don't want to see them, that's who. alt texts are hidden unless needed; titles are not shown until selected in all implementations I have seen; longdesc must be explicitly called up. On the other hand, an image on a page sits there and stares at you. It is not the same as a sound file or a Flash animation that plays as soon as you load a page, but it is in the same category: It's unwanted non-text content. >If text works for you, great, ignore the illustrations. The presence of illustrations alters the layout and continuity of the text and adds text equivalents of its own that may be visible or readable. >Accessibility does not mean removing or minimizing pictorial content. Accessibility means that the removal or minimization of pictorial content must be accommodated. These provisions take into account an absence. The plan to require the addition of images is not the converse. The two are not parallel or equivalent. To sum up a well-argued position: * If WCAG 2.0 requires the addition of IMAT (image or multimedia alternatives to text), people will either ignore the requirement or refuse to comply with any group of requirements, priority level, or module that includes it. * If WCAG 2.0 strongly encourages the addition of IMAT (the terms "whenever possible" will work wonders here), lo and behold page authors will actually do it. * Charles's list of techniques <http://www.w3.org/2001/11/334-wcag> must be considered illustrative; they're a partially helpful how-to listing for befuddled authors who don't know where to begin. It is nonetheless trivial to find counterexamples to many of those guidelines, which betray an anti-*writing* as opposed to an anti-*text* bias. Talented, experienced, and/or professional writers, as actual experts in the practice of writing, will reject the advice outright if it is advanced as a requirement. (WAI has a history of setting requirements and listing examples that are unrealistic and betray inexperience.) * In simple terms, requiring authors to provide text equivalents for images and the like is not the same as requiring them (a) to write a certain way and (b) to use IMAT. In fact, both of those requirements, if enacted, will trigger an unprecedented firestorm of opposition, much of it principled and on the money. Strong encouragement, on the other hand, will actually result in the addition of IMAT to Web pages. As usual, these objections will be immediately and falsely interpreted as calling the entire enterprise of IMAT into dispute. I would say a very strong case has been made that IMAT is necessary. It's *requiring* IMAT and telling people *specifically* how to write that will not work and will incur intense public objections. And now we wait for Gregg to write in about one's "tone." -- Joe Clark | joeclark@joeclark.org | <http://joeclark.org/access/> Accessibility articles, resources, and critiques || "I can't pretend to understand the mind of Joe Clark" -- Larry Goldberg
