although the alternative text for client-side image maps links is not shown in IE and Netscape - they are available if you tab to them. Thus, as well as being available in Lynx, HPR, etc., we decided it was not a problem. As Jim states, however, it is an issue for server-side image maps. Charles - why do you feel the issue needs to be reviewed in regards to non-readers? It seems to me that a non-reader would be using IE or NS with images loaded. If they are using a screen reader, when they encounter a client-side image map the alt-text for each region will be read to them as they tab (we have tested this and it works). Am I wrong to assume that a non-reader would most likely rather view the image map graphic than the alt-text or a redundant text link for each active region? One bit of confusion is that in IE the alt-text of the image map image is displayed as the tooltip. --wendy At 12:56 PM 7/9/99 , you wrote: > > >RN: Hmmm, why are image maps Priority 3?
