Images can be useful, when they supplement text. However, photos, illustrations, graphics, charts, maps, and other types of images present significant obstacles for learners who cannot see the images.
Alternative Text, often shorted to alt text, is key to making images accessible. All non-decorative images need alternative text (alt text) which helps viewers percieve and understand the image's content.
Descriptions are needed, too, for users on a slow internet connection. Without an effective description in place, an image is pointless.
