Web images number 3.2 billion uploads a day while 2.2 billion people have visual impairments, yet automated alt text fails: ImageNet scraped 15 million photos for training but platforms like Instagram and Chrome produce vague or wrong captions — e.g. Chrome labels Porsche 911gt3 and automated alt misses a pregnant woman. Studies report 61% of landing pages with missing alt and error rates up to 35% for dark-skinned females, so the fix is better datasets and writing great, contextual alt text.
