Dear Srs.

Follow my contributions to the document *HTML5: Techniques for providing 
useful text alternatives*

Best Regards
Reinaldo Ferraz

--------------------------------------------------
*Examples of scenarios where users benefit from text alternatives for 
images*
Add:
- They have problems to load images or the source of image is wrong
--------------------------------------------------

Question: In the *Example 2.5*, is it possible to use Image maps 
<map></map> to create alternatives and to put ALT inside of each <area> tag?
--------------------------------------------------

Removing the link *Providing a text alternative that is not null. (e.g., 
alt="spacer" or alt="image") for images that should be ignored by 
assistive technology [WCAG20-TECHS]*. In that way, it would made users 
confused about the meaning (if the user doesnt click on the link)

In the *Example 6.4*, I consider important a short description to the 
image. It´s important even for a blind person or somebody who cannot 
load images perceive that there is an image with a purpose: create a 
medieval atmosphere to the webpage. I disagree that the image with 
description is only related to the blind or low vision webpage. The link 
example shows the users preference 
http://webaim.org/projects/screenreadersurvey/#images

--------------------------------------------------

I belive that *3.11 A group of images that form a single larger picture 
with and without links* is not necessary. the same situation is been 
using at the examples *Example 1.1* and *Example 1.2*

Hi Reinald, 

>Add:
>- They have problems to load images or the source of image is wrong

Words to this effect have been added.

><map></map> to create alternatives and to put ALT inside of each <area> tag?

I have left the link in as I don't understand why its inclusion is confusing. If you would like to explain further please reopen the bug.

I have modified the spec text in Example 6.4
Please review
http://dev.w3.org/html5/alt-techniques/Overview.html#sec6
I have not made it mandatory to provide an non null alt as there are some circumstances where it is appropriate, but do encourage authors to provide a text alternative.
