Hello Jim and All, after getting feedback this what I have to offer on the alt text/title issue: 1) http://www.w3.org/TR/html4/struct/objects.html#h-13.2 "The alt attribute specifies alternate text that is rendered when the image cannot be displayed (see below for information on how to specify alternate text). User agents must render alternate text when they cannot support images, they cannot support a certain image type or when they are configured not to display images." and 2) http://www.w3.org/TR/html4/struct/global.html#title "Values of the title attribute may be rendered by user agents in a variety of ways. For instance, visual browsers frequently display the title as a "tool tip" (a short message that appears when the pointing device pauses over an object). Audio user agents may speak the title information in a similar context. For example, setting the attribute on a link allows user agents (visual and non-visual) to tell users about the nature of the linked resource:" + + + + + + + + + + + + + + + + + + + + + + Tel.: 0611 oder 0163 / 3369925 Homepage: www.barrierefreies-webdesign.de -----Ursprüngliche Nachricht----- Von: w3c-wai-ig-request@w3.org [mailto:w3c-wai-ig-request@w3.org]Im Auftrag von Jim Ley Gesendet: Mittwoch, 16. Januar 2002 12:55 An: w3c-wai-ig@w3.org Betreff: Re: img alt text, links and titles >"Jan Eric Hellbusch": >Actually, neither NS6 nor Opera 5 (available on my system) will show the alt >text of an image as a tool tip, which is the correct interpretation of the >specs. Can I have a reference for these specs? This is clearly not covered in HTML recommendations, it's a UAAG issue, and they don't mandate how alternative content is made available to a user, they just say it should be made available, Tooltip is clearly convenient for many, what accessibility problem does it cause? (Mozilla and Opera cause me problems by not doing it, that's fine they have ways of showing it, I have choice.) >As we have heard from others on this list, the alt text is to replace >the image, i.e. when the image can't be shown due to the rendering software >or when the image can't be found due to incorrect mark up. And UAAG says its sensible and desirable to allow users to show alternative content and content simultaneously (which is obvious, the more representations of a single thing the easier in general it will be to understand - or by showing the ALT content I might "get" the image and then learn for the future what other similar images mean.) Jim.
