What is the use of "alt" attribute in <img>tag?

Question

I am new in html, help me out please!

Answer 1

When the image is taking too long to load or not loading, the text in alt attribute will display in the screen.

alt - - > alternative

For example:
<img src="image.png" alt="Image">

In case the image.png is not a valid file or still loading the "Image" text will be displayed.
