Documentation of accessibility observations for Deutsche Telekom – Mobilfunk & OneShop

1.1.1 Non-text Content (A) Image text alternative does not serve equivalent purpose

Priority: Critical Low Page: Shop Observation Permalink
Accompanying Files
Observation Details

Images that are not purely decorative, must have a purpose equivalent text alternative set, to be accessible if the image cannot be visually perceived. A prime example is a blind screen reader user. But also if an image cannot be loaded due to network issues, the text alternative ensures perception of the conveyed information.

Images with non-equivalent text alternative:

  • "Unser Telekom NextMagenta Unlimited Image", using <div role="img" aria-label="...">

  • "Young Smartphone-Tarife Image", using <div role="img" aria-label="...">

Observations:

  • "Image" is part of text alternative; "Image" will be announced by assistive technology by default and should not be part of the text alternative

  • "Image" is part of text alternative; accessible text is not in main page language

  • Generic <div> element used instead of semantic Image element

  • Image contents are not described in text alternative

Remediation Notes

Ensure purpose equivalent text alternatives are present for every non-decorative image. Depending on the purpose, the text alternative may be describing the contents of an image or the functionality it serves (e.g. as a link to a specific page).
