Description

As an editor I want to create file links with type “static selection of files” and I want to show thumbnails.

Acceptance Criteria:
  • I want to have a field for overriding the alt attribute.
  • A warning is displayed
  • if no alt-text is given - text: “An image must have an alt text if it is not decorative only”
  • if the alt-text includes the filename - “The alt text must not include the filename”
  • if the alt text has more than 100 characters - “The alt text must not be longer than 100 characters.

The warning contains the WCAG rule and a direct link to the explanation of the rule (WCAG rule 1.1.1 - Level A - https://www.w3.org/WAI/WCAG20/quickref/?showtechniques=11%2C111#text-equiv)

Technical Description / Additional Information:
Currently the alt attribute can only be entered in the metadata of the file.
