RE: Longdesc not working

In case it is of use to you, there are add-ons to the browser that will
allow you to view the longdesc without resorting to code reviews:

https://addons.mozilla.org/extensions/moreinfo.php?application=firefox&v
ersion=1.0&os=Windows&id=273 for Firefox
http://www.hackcraft.net/longdesclink/default.asp for Internet Explorer

That said, although we do use longdesc here, and more importantly the
information can be accessed using a screen reader, I find it to be more
useful to simply link to a detailed description of the complex visual
data. The complex image gets a link to it's own web page describing the
content.

Regards,

Norman

Longdesc is not supported by most of the current browsers. It is by
assistive technology though. You are doing the right thing, although the
D link is considered by some to be superfluous.

What do you have in journal25? Longdesc is only needed if the image has
a lot of complex data, like a graph, for normal images it might be more
usable for everyone to have a caption instead underneath the image.
