Re: aria-label vs alt text on linked images

There are lots of reasons why this might happen, such as:

Different methods of navigation, such as tabbing or virtual cursor.
Different behaviours in different versions of the same assistive technology product. These are not usually mentioned in the release notes so you only find them by experimentation.
Different behaviours between browsers.
Different configuration settings in the assistive technology.

Why do you have an "aria-label" attribute if the images have "alt" attributes?

Subject: [WebAIM] aria-label vs alt text on linked images

Hello,

Some colleagues and I are getting different results when using screen readers with linked image that have no link text but have an aria-label attribute in the a tag and an alt attribute in the img tag. (tabbing to the
image)

One colleague is hearing screen readers (VoiceOver, JAWS and NVDA with various browsers) read only the alt text. The rest of us are hearing only the aria-label announced.

What is expected behavior and why might we be getting different results?
We'd like to solve the mystery so we don't have conflicting results in the future.

Thank you,

Patrick
