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: iPhone Erleben Observation Permalink

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 and observations:

  • Main stage image

    • missing text alternative

  • iPhone das ein Bild von einer schönen Rosa macht

    • User takes photo

    • There is no Rose on the photo

    • Typo in "Rosa"

  • Grüner Batterie Icon

    • Typo in "Grüner"

    • Arguably decorative image

  • Telekom Logo mit 5G daneben stehen

    • Arguably decorative image

    • If not decorative, wording could be "Telekom 5G Logo"

  • Blaues FaceID Icon

    • Description of color only important if icon is known

    • Arguably decorative, since Face ID is already mentioned twice

  • Ein iPhone das

    • Missing parts of text alternative

  • Das Icon von der Foto App von Apple

    • Text alternative, if used in alt attribute should rather be concise than using complete sentences; "Apple Foto Icon" would be enough

    • Arguably decorative

  • Apple setzt sich ein für recycelte Materialien

    • Image has text content but text content is not part of text alternative

    • Text alternative is full duplicate of already existing, visible text content

  • Mädchen das mit ihrem Gelben iPhone auf der Wiese liegt

    • "Mädchen" arguably wrong

    • "Gelbes iPhone" not visible

    • "liegt auf Wiese" not part of image

  • Green Magenta logo

    • Mentioning the logo isn't adding any information; if image is not decorative, added information would be a description (e.g. likes of "Hashtag Green Magenta mit einer Sammlung an grünen Blättern")

  • iPhone von von der seite

    • Two devices shows, color not mentioned

    • "iPhone 16 Pro" is text content but not mentioned

    • Typo "von von"

    • Typo "seite" → "Seite"

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).
