Add Alternative Text Descriptions for Images (PPT)
Posted: June 7, 2020 at 9:41 pm, Last Updated: August 15, 2020 at 9:28 pm
Images, charts, and objects within documents should be described using alternative text descriptions. The alternative text (i.e., alt text) is necessary for screen reader users to interpret what information the images are intending to relay.
Alt text only benefits screen reader users. To provide additional understanding for individuals who may have learning/cognitive disabilities, insert a caption.
- Select an image.
- Click on the Picture tab.
- Then select Alt Text.
- Enter the alternative text description (i.e., Alt Text).
NOTE: The Desktop version of Microsoft 365 differs slight. Click on Picture Format > Alt Text in the Ribbon toolbar. Instead of a Format Picture window, the Alt Text window opens (shown below). It includes a field for adding an alternative text description and a checkbox option that allows you to classify the image as decorative (i.e., Mark as Decorative). In other words, the image does not contain beneficial information and, therefore, can be ignored by the screen reader user.
