It's a feature for all websites:

[...]alternative text (alt text) that is to be displayed in place of an element that cannot be rendered. The alt [text] is used for short descriptions[.]

The alt [text] is used to increase accessibility and user friendliness, including for blind internet users who rely on special software for web browsing.
