ALT A screenshot of a post on Mastodon, of a blind person saying that they've been surprised at how more people seem to use alt text to describe their cat pictures on Mastodon than on Twitter. The full text is as follows: As a blind individual, I have to say that #Caturday on #Mastodon is far far more enjoyable then at #Twitter, where the vast majority of cat photos are not described. It is also been fascinating for me to hear descriptions written by those who sent the image, immediately followed by Apple image recognition’s attempts to describe the same image. Only rarely does that add anything to the ALT, & often directly contradicts it. There is no auto magical solution to image description. It is something best done by a human, for only that human can explain the “why” of the image: the reason that image was chosen to speak so eloquently without words for those who can see it. ALT allows you to provide those words.
