Social Security Administration Guide: Alternate Text for Images

Not enough, or too much detail

“Walking”
It’s too little information. We don’t know who’s walking? The dog only, the handler, or both as a team?

“Pastel leads her handler. It is a bright, sunny day and they walk on a garden path with trees and flowers in the background.”
It’s too much information. The descriptive information about the picture does not have anything to do with the context. They could be walking almost anywhere, but the place is irrelevant to the story.

“Pastel leads the way with her handler holding the guide harness in his left hand”.
Just enough information. The text adds information that is not in the surrounding text.
