How do you add pictures

Answer 1

Use the img tag
<img src="exemple.jpg">

Answer 2

Considering you're wondering about how to do so in HTML, there is the <img> tag that displays whatever picture from the internet you need. To add the picture, all you would need to do is add the src attribute to the tag with the URL to the picture you want to use (you can't use pictures that have been downloaded onto your phone or computer).

<img src = "example.jpg">
