The <img> tag defines an image in an HTML page.
The <img> tag has two required attributes: src (web address of the image) and alt (alternatine text which is shown to a user when image can not be loaded because of different issues). Note: images are not technically inserted into an HTML page, images are linked to HTML pages. The <img> tag reserves a space for the linked image. Tip: to link an image to another document, simply nest the <img> tag inside <a> tags.
