The challenge
One of our key clients required accessibility enhancement for a large repository of educational images that lacked meaningful alternative text, affecting usability for visually impaired learners.
- Missing alt text: 35,000 images lacked appropriate descriptions.
- Accessibility compliance risk: exposure to WCAG violations.
- Lack of contextual accuracy: alt text needed educational relevance, not just description.
The approach
- Hybrid alt-text authoring: expert-led manual creation combined with AI validation.
- Contextual layering: image purpose, location and the associated learning content informed every description.
- QA validation: accessibility auditors reviewed the output to ensure compliance.
The results
- 80%+ accessibility boost across the image repository.
- Seamless integration: descriptions delivered into the client’s existing content pipeline.
- Improved learner experience for screen-reader users, with WCAG exposure removed.
