Images can improve the design and the appearance of a web page.

HTML Images Syntax

The HTML tag is used to embed an image in a web page.

Images are not technically inserted into a web page; images are linked to web pages. The tag creates a holding space for the referenced image.

The tag is empty, it contains attributes only, and does not have a closing tag.

The tag has two required attributes:

Syntax

The src Attribute

The required src attribute specifies the path (URL) to the image.

Note: When a web page loads, it is the browser, at that moment, that gets the image from a web server and inserts it into the page. Therefore, make sure that the image actually stays in the same spot in relation to the web page, otherwise your visitors will get a broken link icon. The broken link icon and the alt text are shown if the browser cannot find the image.

Example

The alt Attribute

The required alt attribute provides an alternate text for an image, if the user for some reason cannot view it (because of slow connection, an error in the src attribute, or if the user uses a screen reader).

The value of the alt attribute should describe the image:

Example

If a browser cannot find an image, it will display the value of the alt attribute:

Example

Tip: A screen reader is a software program that reads the HTML code, and allows the user to «listen» to the content. Screen readers are useful for people who are visually impaired or learning disabled.

Image Size — Width and Height

You can use the style attribute to specify the width and height of an image.

Example

Alternatively, you can use the width and height attributes:

Example

The width and height attributes always define the width and height of the image in pixels.

Note: Always specify the width and height of an image. If width and height are not specified, the web page might flicker while the image loads.

Width and Height, or Style?

The width , height , and style attributes are all valid in HTML.

However, we suggest using the style attribute. It prevents styles sheets from changing the size of images:

Example

Images in Another Folder

If you have your images in a sub-folder, you must include the folder name in the src attribute:

Example

Images on Another Server/Website

Some web sites point to an image on another server.

To point to an image on another server, you must specify an absolute (full) URL in the src attribute:

Example

Notes on external images: External images might be under copyright. If you do not get permission to use it, you may be in violation of copyright laws. In addition, you cannot control external images; they can suddenly be removed or changed.

Animated Images

HTML allows animated GIFs:

Example

Image as a Link

To use an image as a link, put the tag inside the tag:

Example

Image Floating

Use the CSS float property to let the image float to the right or to the left of a text:

Example

The image will float to the right of the text.

The image will float to the left of the text.

Tip: To learn more about CSS Float, read our CSS Float Tutorial.

Common Image Formats

Here are the most common image file types, which are supported in all browsers (Chrome, Edge, Firefox, Safari, Opera):

Abbreviation	File Format	File Extension
APNG	Animated Portable Network Graphics	.apng
GIF	Graphics Interchange Format	.gif
ICO	Microsoft Icon	.ico, .cur
JPEG	Joint Photographic Expert Group image	.jpg, .jpeg, .jfif, .pjpeg, .pjp
PNG	Portable Network Graphics	.png
SVG	Scalable Vector Graphics	.svg

Chapter Summary

• Use the HTML element to define an image
• Use the HTML src attribute to define the URL of the image
• Use the HTML alt attribute to define an alternate text for an image, if it cannot be displayed
• Use the HTML width and height attributes or the CSS width and height properties to define the size of the image
• Use the CSS float property to let the image float to the left or to the right

Note: Loading large images takes time, and can slow down your web page. Use images carefully.

If an image fails to load, the alternative text defined on the alt attribute is displayed. However, an alternative image can also be defined with an element.

Try it live Note: If the image provided in the element is also broken, then the inside alt attribute value will be displayed.
