Gregg responded: >I would suggest that it should reflect the function of the line rather than the appearance as in > ><IMG ALT= "Section Divider Line" The inclusion of "Line" in that ALT text seems to be reflective of the appearance to me. ALT="Section Divider" describes the function of the image, but I believe that ALT text is better used as a *replacement* for the image, which usually means that it *provides* the image function rather than describing the function. The distinction between providing the image function and describing the function can be subtle, but I think it's important in the quest for seamless accessibility and device independence. My decision to use ALT="-------------------------" is not based on the appearance of the image at all. Rather, I'm giving this ALT text as a replacement for the image, providing its function--rendered appropriately as a dividing line on text-only browsers and a pause on most speech browsers. (I'm told that some screen readers will say "hyphen-hyphen-hyphen-etc." when encountering such ALT text. My response to this is that these devices are misconfigured. Would they also say "hyphen-hyphen" when reading a sentence like this--with a dash?) If a speech browser's pause is not a sufficient cue for a section change (I believe it would be, but hopefully those more experienced with speech browsers will chime in), then one could also include "End of Section", or, perhaps more seamless, "This concludes the section on Widgets." The hyphens could still be included as an extra aid to visual, text-only browsers: <IMG ALT="---------- This concludes the section on Widgets. ----------"> -- Liam Quinn Web Design Group Enhanced Designs, Web Site Development http://www.htmlhelp.com/ http://enhanced-designs.com/
