Elements containing role="img" have an alternative text

Ensures elements marked role="img" elements have alternate text.

Screen readers have no way of translating an image into words that gets read to the user, even if the image only consists of text. As a result, it's necessary for images to have short, descriptive and accessible alternative text so screen reader users clearly understand the image's contents and purpose.

If you can't see, all types of visual information, including images, are completely useless unless an accessible text alternative is provided which screen readers can convert into either sound or braille. People with low vision or color-blindness disabilities also require accessible alternative text to varying degrees.

Screen readers cannot convert visual image information to speech or braille in the absence of an accessible text alternative associated with the image.
