In our series of Open Educational Resources (OERs), we are today publishing a document on text alternatives for images. Providing text alternatives for images is such a basic accessibility requirement that the Web Content Accessibility Guidelines (WCAG) 2.0 made it their very first Success Criterion. Today’s new OER takes the form of a quiz with 18 questions that cover various types of images that require different types of text alternatives. It is available on Google Drive (Microsoft Word format).
Learners and educators who want to find out more about text alternatives can refer to many other resources, for example:
- WCAG‘s support document Understanding SC 1.1.1,
- WCAG‘s support document How to Meet SC 1.1.1 (which lists techniques and failures),
- HTML5: Techniques for providing useful text alternatives (this document can still evolve).
