Html image help

Question

body>
<img src="tree.jpg" alt="" />
</body>

In this piece of code what is the alt=“”/> used for? What might it ever change to?

Answer 1

alt is used to show the text when the image is not displayed.

Answer 2

This information should have been called out on the second slide of the HTML images lesson:

The alt tag is also useful for accessibility purposes (for the visually impaired, e.g. if blind people use software to read the website to them) and for SEO (supposedly).
