Add Alternative Text to Images in Blackboard
When creating content in the Blackboard Content Editor (the WYSIWYG text editor), it is important to tag images properly with alternative text so they are readable and accessible by individuals with disabilities.
Alternative Text (Alt Text)
Everything you need to know to write effective Alt Text - guidance and tips from Microsoft.
Alternative text provides a textual alternative to graphics and images and serves several functions:
- The alternative text can be read audibly, allowing the content and purpose of the image to be accessible to those with visual or certain cognitive disabilities.
- Text is displayed in place of the image if the image file is not loaded or when the user chooses not to view images in their browser.
- Computers and assistive technologies cannot analyze an image and determine what it is without alternative text.
Alternative text should:
- describe the image and its purpose
- include important text from the image
- be accurate
- be briefly and clearly expressed
- not be redundant
- not use the phrases "image of..." "graphic of..." or "logo of..." to describe the image
- not be over 125 characters (most screen readers will stop reading after reaching 125 characters)
