Accessible Image Sample Book

The Accessible Image Sample Book, created by the DIAGRAM Content Working Group, is a free online resource that shows you what some of the many options are for creating accessible versions of digital images such as:

  • maps
  • bar charts
  • diagrams
  • mathematical expressions
  • photographs
  • and more!

Each of the ten chapters in the book shows a different complex image in context of the book it came from, along with helpful tips and the code used to provide the accessible image in a digital book. See (and hear!) the different ways that an image can be made accessible, including:

  • short and long descriptions
  • tactile graphics
  • MathML
  • sonification
  • audio description
  • 3D printing

This resource can be used as a guide when creating accessible images in your own digital books and other digital publications. You can learn more what the book contains by listening to the webinar about the Accessible Image Sample Book presented by its authors.
