Quick image resizing lesson.
You can use the modifier width="xxx" to make an image xxx pixels wide. Aspect ratio of the image will remain the same.
Or you can use the modifier height="xxx" to make the image xxx pixels high. Aspect ratio of the image will remain the same.
Or you can use the modifier width="xx%" to make the image xx% of the width of the browser window. This is handy as it will automatically resize the image to whatever size the browser window happens to be.
So, typing <img src="https://nypost.com/wp-content/uploads/sites/2/2023/03/NYPICHPDPICT000007831829-1-edited.jpg" width="200"> gives us:

And typing <img src="https://nypost.com/wp-content/uploads/sites/2/2023/03/NYPICHPDPICT000007831829-1-edited.jpg" width="75%"> gives us:

The first image will remain 200 pixels wide no matter the size of the browser window. The second image will automatically resize to 75% of the width of the browser window as you resize the browser.
There ends today's HTML lesson. (Mostly because I've now exhausted my HTML knowledge...)
Thanks! So the image resizes length automatically and in proportion........
