Add rich descriptions to images to improve comprehension
Images can help communicate complex ideas to students. For students with visual impairments, image descriptions that explain the content of an image are crucial for their learning. For all students, text descriptions can provide deeper context to aid their comprehension.
Image descriptions are commonly known as “alternative text” or simply “alt text”. This is because they provide a text based, descriptive alternative to the image.
Blackboard Ally checks for image descriptions anywhere there is an image. This includes image files and files (such as documents and presentations) that include images.
If an image is only for visual effects and does not contain information relevant to the learning content, the image can be marked as decorative. This helps assure students of the purpose of those files.
Watch the Web Accessibility Design Principles video on the (use of) images.
