Definition and Usage
The <img> tag is used to embed an image in an HTML page.
Images are not technically inserted into a web page; images are linked to web pages. The <img> tag creates a holding space for the referenced image.
The <img> tag has two required attributes:
- src - Specifies the path to the image
- alt - Specifies an alternate text for the image, if the image for some reason cannot be displayed
Note: Also, always specify the width and height of an image. If width and height are not specified, the page might flicker while the image loads.
Tip: To link an image to another document, simply nest the <img> tag inside an <a> tag (see example below).
