Add a written description of images to make your presentation accessible to those who are blind and rely on a screen reader. For a photo, artwork, or a poster, describe the image. Guidelines for writing good alternative (ALT) text recommend no more than 125 characters. However, if you are describing a poster, include all of the poster text in the description box.

Also, you may want to write a brief article to go along with an image and include a list of references.

This is an image of a gray tree frog on the railing of my deck. It is lime green and gray and can change to camouflage itself. In the photo, it is sitting on a yellow leaf.

There are two species of gray tree frogs…  This could be a short article about gray tree frogs with a list of references.
