This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
<a href="http://w3.org"> <img src="images/w3c_home.png" width="72" height="48" alt="W3C web site"> </a> This is a good example of WCAG 2.4.4 descriptive linked text... Perhaps have a second example with no anchor, where it is just a flat logo image <img src="images/w3c_home.png" width="72" height="48" alt="W3C logo"> I have a blind friend that mentioned to me that she likes to know it is a logo, rather than just the company name in the alt text. alt="CanAdapt logo" the word logo of course is optional, leaving logo off would also be sufficient... but I don't think we should give the impression that we have to leave the word "logo" off in a non-linked logo image... ie sponsorship pages etc... (of course perhaps these days it is hard to find a non-linked image of a logo on the web.) would like other's opinions.
Regarding the alternative text mentioning what type of image it is.. there's some limited data from the WebAIM survey http://webaim.org/projects/screenreadersurvey/#images under "Identification of photos". It states a general preference of survey takers to know that the photo image is specifically a photo. The best place to find an unlinked logo would probably be in the footer of the company owning the logo, though I don't have an in-the-wild example at hand.

For more details, see this document: http://dev.w3.org/html5/decision-policy/decision-policy.html Status: Accepted Change Description: see commit https://github.com/w3c/html/commit/3b7fc6a65b1f1b02ec683324cf6bb8d6edc4ac7e Rationale: data was provided that users find this information useful (Comment 1) --
CURRENT FIX <p class="note">If the significance of the the image being a <em>logo</em> is considered important to convey to users who cannot view the image, the text alternative in the example above could also include such information. It is suggested that square brackets be used to delineate this information: <code>alt="[logo] WebPlatform.org"</code>.</p> SUGGESTED FRIENDLY AMENDMENT -Remove the double "the" in the first sentence. OR Rather than forcing authors to make a judgment call about whether it is important. How about simply providing it as an parallel option of which is just as viable? <p class="note">The text alternative in the example above could also include the word "logo". If so, it is suggested that square brackets be used to delineate this information: <code>alt="[logo] WebPlatform.org"</code>.</p>

If so, it is suggested that square brackets be used to delineate this information: <code>alt="[logo] WebPlatform.org"</code>.</p>
