Hi,
I'm a young guy at WebAIM Forum. I really appreciate the discussions.
I work in Lisbon, Portugal, in the field of Web Accessibility at the
Ministry of Science & Technology. Since August 1999 that Portugal
have legislation about Web Accessibility applied to Public
Administration.
More recently I bought the "The WebAIM guide to Web Accessibility
Suite". Is a great content! congratulations to WebAIM team. I
recommend it :)
This tutorial recommend 4 Methods of Providing a Long Description:
- In the context of the document itself;
- A normal text link;
- The longdesc attribute;
- "D" links.
I'd like to know your opinion about a 5th possibility:
- the image is a link to it's description.
In code, I mean:
<a href="description.htm" title="Description of ..."><img src="..."
alt="short description, <= 80 chars according with Cynthia Says
Report :) " /></a>
What do you think? Semantically seems me adequate: a description is a
closer view.
Like the methods listed above are ordered, what could be the order of
this "solution"? Or isn't either a "solution"...
Kind Regards, Jorge Fernandes

Jorge,
What happens when you are trying to use the image to link to something other
than the longdesc?

Steve,
If the function of image is to link to something, maybe it don't need
a longdesc...

A good example of this diference could be an institucional logo in a
website:
At homepage:
<a href="description.htm"><img ... longdesc="description.htm /></a>
At the others pages:
<a href="index.htm"><img ... alt="Homepage" /></a>

Does a logo *need* a long description? I would have thought that alt
text would be sufficient.
Also, conventional behaviour is for the logo to link to the homepage
(as you have done on the other, non-home, pages). Usability best
practice says not to link to the current page, so I would think that
the best thing would be to have the logo without a link on the home
page.

It doesn't, and it is surely misleading and potentially quite confusing to
make a logo, used otherwise normally as a logo, a link to a description of
the logo.
If you have something to say about the design of a logo, then you can say
that on separate page, or in a separate section of some page. Any link
pointing to it should we written along normal link text design principle:
descriptive, concise, and distinctive. "About our logo" or "Description of
the ACME logo" might work.

I'd say that the alt should be the name of the company (i.e. the alt serves the function/purpose of the logo, which is to communicate which company site we're on), while longdesc describes the appearance of the logo itself (although in most situations I'm not sure this is necessary, unless we were creating a page which discusses the visual appearance and differences of logos, for instance, where this information is essential to the understanding of the rest of the page).

In my experience, LONGDESC is only necessary for graphs and survey
results, where longdesc links to a tabular representation of the same
data.

I have used longdesc as a link to an html page when using a graphic of
an announcement. I.e. when we have a flyer graphic that I have put on a
page, I have a longdesc that links to a text only version of the
announcement.

As a mark of respect to low-vision people, I'm using it for a photo
gallery as well. And it's interesting for me too, because I have to find
a way to understand the 'theory' underlining the picture.

Sorry. Just to focus the question. The question is, when we need a
longdesc to an image, how to put it?
The tutorial "The WebAIM guide to Web Accessibility Suite" recommend
4 Methods of Providing a Long Description:
- In the context of the document itself;
- A normal text link;
- The longdesc attribute;
- "D" links.
I'd like to know your opinion about a 5th possibility:
- the image is a link to it's description.
In code, I mean:
<a href="description.htm" title="Description of ..."><img src="..."
alt="short description, <= 80 chars according with Cynthia Says
Report :) " longdesc="description.htm" /></a>
What do you think? Semantically seems me adequate: a description is a
closer view.

I got already a thought of Steve "What happens when you are trying to
use the image to link to something other
than the longdesc?". Theoretical he's right but I answer "If the
function of image is to link to something, maybe it don't need a
longdesc...".
