Images can provide valuable information in a document. By providing Alt Text descriptions, a screen reader can provide that valuable information. Alt text should adequately describe what is being displayed and why it’s important. This allows screen readers users to benefit from the information being conveyed by the image, even if they cannot see it.
How to create Alt Text
- Right click on the image and select Format Picture
- Select the icon with the 4 arrows and click on the Alt Text to open the appropriate field
- Enter the image description in the description field (not the Title field)
Refer to this Pubcom.com's Alt Text guide.
Images not being used to convey content may be marked as "decorative" in documents and within a Blackboard Learn page. Images can be marked as “decorative” wherever the Alt Text is entered.
Describe graphs and complex images using a table caption or brief descriptive text. A complex image is one that requires more than 150 characters to describe within alt text.
