CP 3.5 – Provide Alt text for each image
For Office documents, you can add text alternatives by right-clicking the image and choosing ‘Edit Alt text’, or by selecting the image and clicking the ‘Alt Text’ icon on the ‘Picture Format’ ribbon.
If the image is purely decorative then mark it as decorative
- For Office documents, you can specify decorative images by checking the “Mark as decorative” checkbox in the Alt Text pane. Note: although there will be no text in the textbox, it is essential that you check this checkbox as this communicates the image’s decorative nature to screen readers.
For all other instances, use alt text that accurately describes the content of the image.
- Type the Alt text into the box in the Alt Text pane;
- Alt text is always dependent on the context of the image and the available text around it. There is a very good illustration of this on WebAIM’s alternative text page
- Read CP 1.3.1 - All images must have a text equivalent for further guidance on Alt Text.
