Almost all social media platforms, including Facebook, allow you to write or edit an image's alternative(Alt) text. Facebook auto-generates Alt text over every picture you post. However, the automatically generated text often bears little resemblance to the actual image, meaning not all of your users can experience your photos as you intended.
