Requirement: All images must carry alt tags.
Why is this required? If an image is published without an alt tag then a screen reader would inform the user that there is an image on the page, but would not be able to give them any information about it, causing frustration.
Exceptions: If images are decorative or a background CSS image, then the alt tag must be left empty (i.e. alt=””).This tells the screen reader to skip the image. If an image has a caption with a sufficient description, then it is acceptable to leave the alt tag empty.
Requirement: when image links are adjacent to text links to the same destination, the image and text links MUST be combined and an empty alt tag used.
Why is this required? This reduces the number of links that screenreader users and keyboard users have to navigate
