Images: Alternative Content for Accessibility

Do you know how to write good alt text? Learn the basics, best practices & advanced techniques for creating accessible images.

April 19, 2021 · 10:00 AM to 11:30 AM CT

Creating accessible images is both a science and an art. The science reveals when you need alternative text and the techniques to use. The art is crafting alt text that helps screen reader users connect and engage. Learn both from Knowbility’s accessibility experts!

Our accessibility analyst Emily Lewis will teach the foundation of accessible images. She’ll dive into WCAG requirements, best practices and techniques for simple vs. complex images. You’ll learn:

  • The difference between decorative, functional and informative images
  • Plain language tips for writing good alternative text
  • Development techniques for providing alternative text for complex images like charts and graphs
  • Who on your team is responsible for accessible images

You’ll also learn about the user experience from our communications specialist Anthony Vasquez. He will demonstrate examples of “bad” alt text and explain the impact on screen reader users.


In celebration of the 35th anniversary of the screen reader, the cost of this webinar is just $35!
