Many of the pictures that you encounter on the Internet include something called alternate text, or “alt text.” This is a description of the picture that is added to it which allows a screen reader, as well as some other mechanisms, to be able to determine the contents of the picture. This is very common for helping visually-impaired individuals to consume visual media.
You can also add alt text to pictures in Powerpoint 2010 slideshows if you know that some members of your audience might read your slideshow in a way that the alt text could be important. Our guide will show you how to add alt text to a picture in a Powerpoint 2010 slideshow.
Where to Add Alternate Text in Powerpoint 2010
The alt text attribute is something that is set individually for each picture in your slideshow. Screen reading tools are not able to describe or determine the contents of an image, so you will need to add a title and description for the image into a special Alt Text section of the picture formatting menu.
Step 1: Open your slideshow in Powerpoint 2010.
Step 2: Click a slide containing an image to which you need to add alt text.
Step 3: Right-click the picture, then select the Format Picture option.
Step 4: Click the Alt Text option in the left column of the Format Picture window.
Step 5: Type the title for the picture into the Title field, then type a description into the Description field.
Step 6: Click the Close button at the bottom of the window when you have finished.
