Missing alt text in image of PowerPoint

Question

How do I correct missing alt text in an image on PowerPoint?

Answer

This error states that the image used in the document does not have alternate text. Alternate text helps readers understand information presented in pictures and other objects. This tool is essential when the viewer is visually impaired or the image is unavailable.

1. Microsoft PowerPoint will navigate you to the image that needs alternate text when you click on it in the Accessibility checker
2. Right click on the image and select Format Picture 
3. Select the Layout & Properties tab (third tab)
4. Click Alt Text
5. Type in the alternate text for the image in the description field
   1. If you have a detailed image that requires a long description, you may want to enter a summary of the description in the Title field. This allows users to decide if they need the full description of the image or not. Otherwise, you can leave the field blank
6. Close the Format Picture windowpane

Your alternate text has now been saved and that error will automatically be removed from the Accessibility Checker Inspection Results
