9. HTML Images - The <img> Tag and the Src Attribute • In HTML, images are defined with the <img> tag. • The <img> tag is empty, which means that it contains attributes only, and has no

closing tag. • To display an image on a page, need to use the src attribute. Src stands for

"source". The value of the src attribute is the URL of the image that want to display.

• Syntax for defining an image:• <img src="url" alt="some_text"/> Example from UPM Home Page• <tr><td width="4"><img src="image/dotkhas.jpg"></td><td width="100%"><a

class="one" href="?kat=D&aktvt="><span id="khas1">Inspirasi NC</span></a></td></tr>

• The URL points to the location where the image is stored. An image named " dotkhas.jpg ", located in the "images" directory on "www.upm.edu" has the URL: http://www.upm.edu/images/boat.gif.

• The browser displays the image where the <img> tag occurs in the document. If you put an image tag between two paragraphs, the browser shows the first paragraph, then the image, and then the second paragraph.
