How do I add descriptive text (ALT) for images in my PowerPoint (.ppt)?

This works on Windows computers only.

Open PowerPoint.

1.      Go to the slide where the image resides. 

2.      Right click on the image and choose the “Size and Position” option from the popup menu. (If you don't see it in the menu initially, try pointing to one of the selected image's "handles" and right click again.)

In the new window, select the ALT text tab and add the text you need to instructionally describe the image.
