Twitter has made it possible to add descriptions (Alt Text) to images and GIFs. Making them more accessible to people with vision impairments. It will eventually be switched ON by default, but for now we must turn it on.
I was looking at what accessibility features Twitter had, and found the 'compose image description' option. Being a lover of Alt Text in HTML I started using it, now I'm trying to spread the word so more people activate it. I've been informed it will be switched on by default, this is currently being worked on.
