To make your presentation accessible, you need to include alternate text for any images and objects in your presentation. This is so that screen readers can have a description of the image to read out loud. To create alternate text, you must
1. Right click on the image.
2. Click Format
3. Go to Alt Text
4. Enter a Title and Description in the box. Make it concise, but also make it long enough to explain what the image is.
5. Close it out.
Note: Also include alt text for objects that do not have text, such as straight line connectors or a shape without text inside of it.
