img Tag and the src Attribute
Images are added to a site using the < img > element, which has to carry at least two attributes: the src attribute, indicating the source of the image, and an alt attribute, which provides a description of the image.
<img src="logo.gif" alt="default text" / >
The src Attribute
The src attribute tells the browser where to find the image. The value is a URL and, just like the links, the URL can be an absolute URL or a relative URL.
The alt Attribute
The alt attribute must appear on every <img> element and its value should be a text description of the image.
The height and width Attributes
<img src="logo.gif" alt="default text" height="120" width="180" / >
Background Images
consider the following code for background image.
<html> <title>HTML images</title> <body background="image1.jpg"> <h3>text on background image</h3> <p>Both gif and jpg files can be used as HTML backgrounds.</p> <p>If the image is smaller than the page, the image will repeat itself.</p> </body> </html>
