In theory, a Flash site should be as accessible as an HTML site; if it provides all the accessibility features that HTML provides, such as alt attributes, keyboard access, synchronized captions for any audio that conveys content, allowing the content to scale to a larger sizes, valid code, links, separating presentation from content, etc. Some flash content even has the potential to aid people with learning or cognitive disabilities. And yes, the more modern versions of screen readers can render it. However, those screen readers can be very expensive, and many users' financial situations preclude even upgrading. There are still a great many people using legacy screen readers out there. In time most people who use screen readers will have software that plays nice with Flash. Until then, though, my advise continues to be to avoid Flash or, if it must be used, to make sure a user has a chance to opt out of it for an accessible page before the Flash begins. Currently the only way to be 100% forward and backward compatible is to create an accessible HTML version of a Flash site. Or only use it for nonessential parts of a web site. Also Flash makes it harder for a site to rank well on the search engines. As far as I know, there are no search engine bots/spiders which can read the contents of Flash. So if you are concerned with SEO you need to include alternative content (ie. text, html) for any Flash content.[2] Best Regards, Laura [1] http://webaim.org/techniques/flash/ [2] http://www.alistapart.com/articles/flashmxmoving/ ___________________________________________ Laura L.
