This video demonstrates how to activate and use image descriptions on Twitter, from the mobile and desktop sites. These are very important for visually impaired people, as it enables them to understand, enjoy and interact with your content more fully.
On the mobile version of Twitter, go to your profile and click on the gear icon to bring up the menu of options. Click on Settings. Under General at the bottom you’ve got an option for Display and Sound, and in there is an option for Accessibility. And in among the options there, at the very bottom, is Compose Image Descriptions. Turn that on.
And on the desktop site it’s very easy as well. Click on your profile picture at the very top right on the menu bar, and pick Settings and Privacy from the menu. Then, in all the options on the left hand side, go down to the bottom and click Accessibility. Again you’ll see a tick box there for Compose Image Descriptions, so just enable that.
Now, when you go to compose a tweet and insert a picture, you’ll get an option to Add Description at the bottom. You get 420 characters to do this, so it’s a fair bit of space. Just use your judgement as to what is important for people to understand about the image. Don’t go overboard, but try to help them to visualise in a reasonable way.
It’s a very important and easy feature to activate and use, so it’s well worth doing. 🙂
