Rule 3: Alt texts
The page contains a large number of images, mostly with
adequate or tolerable alt texts:
- There are small
images for layout between the language links (the first set of navigational
links). They have alt="". However, alt="|" would be
better, since the logical role of the image is that of a separator.
- Other images
used for layout purposes adequately have alt="".
- The images that
act as language links have the name of the language in English as the alt text,
e.g. alt="Arabic". This is quite acceptable.
- The image
containing the WHO symbol and logo and acting as a link to the main page has
alt="WHO Home". This is tolerable, but as mentioned above, a longer
text would be better. As written, the image and the alt text are not really
- The link
“printable version” is preceded by a small icon that is also a link
– to the same page. This is not good practice, and it also implies that
the first of these links is an image with an empty alt attribute. It would be
better to make the icon and the text one link (
href="print.html"><img … alt=""
border="0" />printable version</a>).
Checking all those alt attributes is somewhat awkward. The
extensive use of layout images makes it harder to find other images and check
their alt attributes. The page would benefit from using a more modern approach
to visual formatting, style sheets (CSS).
