HTML Getting Started Tutorial)

To display images on the page, you need to use the source attribute (src). src refers to "source". The value of the source attribute is the URL address of the image.

The syntax for defining an image is:

<img src="url" />

URL refers to the location where the image is stored. If an image named "boat.gif" is located in the images directory of www.w3school.com.cn, its URL is http://www.php.cn/images/boat.gif.

The browser displays the image in the document where the image tag appears. If you place an image tag between two paragraphs, the browser will display the first paragraph first, then the image, and finally the second paragraph.

Replacement text attribute (Alt)

The alt attribute is used to define a string of prepared replaceable text for the image. The value of the replacement text attribute is user-defined.

<img src="boat.gif" alt="Big Boat">

When the browser cannot load the image, the replacement text attribute tells readers the information they lost. At this point, the browser will display this alternative text instead of the image. It's a good practice to add the alt text attribute to all images on the page. This helps display information better and is very useful for those who use text-only browsers.
