What should I do to help my code visualize this image?

So for starters, I would like to say that I use the Atom text editor while using HTML. I am also a beginner so please give an easy explanation. Now here is my code:

<html>

<head>

<text>My Schedule</text>

</head>

<body>

Well........ Here is my schedule I guess. Let us begin the presentation. Let the show begin!

<sup><h1>My Coding Schedule</h1></sup>

<i><h3>My average day</h3><i>

<img src="code-1839406_1920.jpg" alt="cool coding image" />

</body>

</html>

Here is the image I used: code-1839406_1920.jpg

Edit: I did put the image on the HTML folder

Once I did this, I got no image on HTML. Why?
