HTML Images - Image tag (<img>) and source attribute (Src)

In HTML, images Defined by the <img> tag.

<img> is an empty tag, which means that it only contains attributes and has no closing tag.

To display an image 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 images is:

<img src="url" alt="some_text">

URL refers to the location where the image is stored. If an image named "../style/images/boat.gif" is located in the images directory of m.sbmmt.com, its URL is //m.sbmmt.com/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.

HTML Image - Alt attribute

alt attribute is used to define a string of prepared alternative text for the image.

The value of the replacement text attribute is user-defined.

<img src="../style/images/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.

HTML Image - Set the height and width of the image

The height (height) and width (width) attributes are used to set the height and width of the image.

The default unit of the attribute value is pixels:

<img src="../style/images/pulpit.jpg" alt="Pulpit rock" width="304" height="228">

Tip: It is a good habit to specify the height and width of the image. If an image has a specified height and width, the specified dimensions will be retained when the page loads. If the size of the image is not specified, the overall layout of the HTML page may be destroyed when the page is loaded.

Basic Notes - Helpful Tips:

Note: If an HTML file contains ten images, then in order to display the page correctly, it needs Loading 11 files. Loading images takes time, so our advice is: use images with caution.

Note: When loading the page, pay attention to the path to insert the page image. If the position of the image cannot be set correctly, the browser cannot load the image, and the image tag will display a broken image.
