ImageDos - Fluentui — ContextQMD

Provide descriptive values for the alt text attribute for all images. If alt text isn't provided for images, the image information is inaccessible, for example, to people who cannot see and use a screen reader that reads aloud the information on a page.
Consider context. If the image represents a function, be sure to indicate that. If it is to be consumed with other objects on the page, consider that as well.
Make the description brief but accurate. Use one sentence, two at the most.
