10.5.1. Alt-text

Some users might not be able to see images on websites for a variety of reasons. The user might be blind or low-vision. Their device or internet connection might not support images. Or perhaps all the images got deleted (like what happened to The Onion).

In order for these users to still get the information intended from the images, the image can come with alt-text. You can read more about alt-text in this New York Times feature

Twitter lets users provide alt-text for images they post, but they aren’t required to do so.

What we will do next is search twitter for posts with images and see which ones have alt-text. But before we do that, we need to look at how to access extra information, like image information, using Tweepy.
