HTMLImageElement <img>

The properties and methods used to edit image elements are provided via the HTMLImageElement interface, which represents an HTML <img> element. Images are linked to internet pages; they are not actually placed into web pages. The relevant picture is held in place by the <img> element.

Note: Additionally, you must always give the image's width and height. The website can flicker while the image loads if the width and height are not provided.
Tip: Simply nest the <img> tag within  <a> tag to attach an image to another document.
