Alternative text or alternative text is an important way to make the web more accessible for people with visual impairments. With Twitter, you can make sure a wider audience understands your tweets by adding alt tags to your images when you upload them. Here’s how to do it.
Add alternative text with the Twitter mobile app
If you are using the Twitter app on your iPhone, iPad or Android device, adding alt text is easy. First, open the Twitter app on your device. Compose a new tweet and add an image. When you see the preview of the image, click the “+ ALT”
After that, Twitter will ask if you want to add a description to your image. Click on ‘Sure’.
Then type the description you want to add. Good alternate text descriptions describe what is literally in the image so that people who may not be able to see the image can understand what people are saying about it and why it is being shared. Tap Done when you’re done.
Your alt text has been registered. Then tap “Tweet” to tweet the image.
Your tweet with alt text has been shared with the world. Just repeat these steps every time you share an image and you’ll make the online world more accessible.
Add alternative text with the Twitter desktop site
Adding alternate text via the Twitter website is also easy, but the procedure is slightly different from mobile apps.
First, visit Twitter.com in your favorite browser. Then start composing a tweet as usual and then add an image to your tweet as you normally would. Once you see the preview of the image, click “Add Description”, which is located just below the thumbnail.
In the “Description” box that appears, type a good description of the image you just added to the tweet. Good alt text usually contains a concise literal description of what is in the image. Then click on “Save” in the top right corner.
Your description has been saved and you will see it just below the thumbnail of the image. When you’re done, click on ‘Tweet’.
Your masterpiece has now been shared with the world, and anyone reading Twitter with a screen reader will no doubt appreciate that you took the time to add a brief description of your image. Have fun out there!
