All images regardless of their complexity need to have an Alt text in some way. Alt Text is a brief description of your image that is 150 characters or less. This Alt Text is meant for any image that has meaning within the context of the document. Screen readers cannot read images to the reader, so Alt text acts as a substitute. To add an Alt Text to your image,
Right-click the image and select Edit Alt Text.
Type the alt text in the menu that pops up to the right. Use 150 characters or less.
If the image is decorative, write the word Decorative as the alt text (do not check the box that says "Mark as decorative").
