Description Janina Sajka 2013-09-11 04:56:19 UTC
Section 4.8.1.1.3 explicitly uses a logo in its examples, but the alt text provided does not include the term "logo." This is useful information that should be indicated by alt text. As a general rule, a clearly identifiable image class should be indicated in alt text along with a terse indication of the image's purpose on the page.

Hi janina, is there a best practice reference for the "general rule" you describe? As it would be good to be able to reference it from the HTML spec.

The image's primary purpose in this case is as link text, adding descriptive information about the image itself in this case does not seem appropriate as it makes the link text ambiguous (is this a link to a logo?)
