Since accessibility continues to be at the forefront of conversations in education, it is important to discuss accessibility challenges that are encountered. One such challenge is found in the lack of alt tags for images in PowerPoints and PDFs. When assistive technology is used, images without alt tags are difficult to decipher and any educational value can be lost. This leaves the individual with an unequal opportunity for learning. To address this problem, alt tags are used as concise and clear descriptions of the image which are readable by assistive technology. For information on how to add alt tags to images in instructor-created PDFs, follow the steps in PDF Accessibility Check to help identify and fix alt tag issues. You can also review the short tutorial video on How-to Create Alt Tags for Images in Blackboard.
To include alt tags in PowerPoints, try the following actions.
1. Right-Click the image and select “Format Picture.”
2. Select the “Size and Properties” tab and expand the “Alt Text” area.
3. Type in a concise and clear description of the image into the title and descriptions areas.
