How to make Images Accessible?
Images are a really great instructional resource, but what if the student can’t see the image?
Luckily we have a couple tricks we can do to make images accessible. The minimum requirement is that all images have alt text (or alternative text), which is a piece of code that provides a description to users who cannot see the image.
For complex images, we might have to use surrounding text, which is just simply text in the body of the document or page that describes the image in greater detail.
Alt text and surrounding text (if needed) should provide:
- Context – What is the image of? Why is it important? What instructional objective or concept should the student gain from this image? Keep in mind this will depend on the image itself as well as how it is used. For example, a painting of Napoleon might have different alt text in a history course versus what it would have in a painting class. Always go back to why you are using the image, and what learning objective it is accomplishing.
- Function – Is the image a link? Or does clicking on the image do an action?
How to add alt text in Microsoft Office?
To add alternative text to images in your office documents, left-click on an image to select it. Then, if you’re on the desktop version of a Microsoft Office, click on the “Picture Format” tab. If you’re on the online or web versions of Microsoft Office, this tab will be called “Picture”.
Next, click on “ALT TEXT” from the Ribbon Menu. to enter the description for the image. The title field is optional!

Example of Surrounding Text
The following is an example of an image that has surrounding text and alt text, remember the alt text is normally invisible:

In 1806, Jean Auguste Dominique Ingres created a painting that was a recreation of Napoleon I during his enthronement.
ALT TEXT: Napoleon I on his Imperial Throne
Keep in mind, your surrounding text and ALT Text should always focus on the learning objective or why you are using the image.
