Hi Arron,

It is up to you, i.e., to the assistive technology! For example, Home Page
Reader renders a link "Long Description" next to the image with
href="graph1.htm" from your example. I would think that would make sense for
a screen reader too.

Subject: LONGDESC


I find myself suddenly confused about the LONGDESC attribute. According to
http://www.w3.org/WAI/wcag-curric/sam3-0.htm, the LONGDESC attribute
resides in an image tag such as the following:

<IMG SRC="graph1.gif" LONGDESC="graph1.htm" ALT="3-d sales chart.">

But when is access to graph1.htm presented to the user? Is this IMG
supposed to be a link to graph1.htm? Is the UA supposed to render a D link
to the LONGDESC URI immediately following the IMG object? Is an AT supposed
to simply announce the URI? I assume that the average user isn't supposed
to view the source, copy the URI. and paste it into the address edit box
just to find the LONGDESC text, right?

Can someone educate me?

Thanks,
