Verify image is decorative

Definition Verify an image with [alt=""] or [role="presentation"] is only being used for purely decorative, spacing or stylistic purposes.
Purpose
  • If an image is used purely for stylistic or decorative purposes, users of screen readers do not need to know that the image exists and no alternative is needed.
  • If an image contains information, but is mistakenly identified as decorative, users of assistive technologies will not have access to the information.
