GitHub(@github):Most alt text checkers confirm that an accessible name exists, but not that it says anything useful. So alt="IMG_2847.png" passes, and so does the same rating text pasted onto five different star icons. More than one in four images on the top million home pages have alt text that is missing, vague, or duplicated from a neighbor. That's why we built an alt text plugin for the GitHub Accessibility Scanner.
