HTML Images
The HTML <img> tag is used to embed an image in web pages by linking them. It creates a placeholder for the image, defined by attributes like src, width, height, and alt, and does not require a closing tag.
There are 2 ways to insert the images into a webpage:
- By providing a full path or address (URL) to access an internet file.
- By providing the file path relative to the location of the current web page file.
We will first discuss inserting the image into the webpage & simultaneously, we will understand both the above approaches.
Adding images on a webpage:
The <img> tag embeds images in web pages, requiring only attributes without a closing tag. Images enhance design and content quality, linked via the <img> tag to preserve space and optimize webpage performance.
Syntax:
<img src="url" alt="some_text" width="" height="">
Attribute: The <img> tag has following attributes:
Attribute | Description |
---|---|
src | Specifies the path to the image file. |
alt | Provides alternate text for the image, useful for accessibility and when the image cannot be displayed. |
crossorigin | Allows importing images from third-party sites with cross-origin access, typically used with canvas. |
height | Specifies the height of the image. |
width | Specifies the width of the image. |
ismap | Specifies an image as a server-side image map. |
loading | Specifies whether the browser should defer image loading or load it immediately. |
longdesc | Specifies a URL to a detailed description of the image. |
referrerpolicy | Specifies which referrer information to use when fetching the image. |
sizes | Specifies image sizes for different page layouts. |
srcset | Specifies a list of image files to use in different situations, allowing for responsive images. |
usemap | Specifies an image as a client-side image map. |
src attribute:
The src attribute in <img> tag specifies the image’s location. If the URL is correct, the browser retrieves and displays the image; otherwise, it shows a broken link icon.
Example : In this example we displays an image using the <img> tag with src attribute pointing to a w3wiki logo. It enhances content by visually representing the website’s identity.
<!DOCTYPE html>
<html>
<head>
<title>Welcome To GFG</title>

alt attribute :
The alt attribute in <img> tag provides a text alternative if the image fails to load. It aids accessibility for users unable to view images due to slow internet, src errors, or screen reader usage.
Example : The example illustrates the use of the alt attribute in the <img> tag.

The width and height attributes are always declared in pixels. Please refer to the How to set the width and height of an image using HTML? article for further details.
Example: In this example we sets the width and height of an image using the <img> tag’s width and height attributes. It showcases the w3wiki logo with dimensions of 300×300 pixels.

Setting style to the Image:
In this example, we are using the border property to decorate the image. By default, every picture has a border around it. By using the border attribute, the thickness of the border can be changed. A thickness of “0” means that there will be no border around the picture. Please refer to the HTML | <img> border Attribute for further details.
Example: This example illustrates the use of style property inside the <img> tag in HTML.
<!DOCTYPE html>

Adding Image as a Link:
To add an image as a link, enclose the <img> tag within an <a> tag, setting the image’s source with the href attribute. This creates a clickable image linking to external content, such as images, videos, or other web pages.
File paths are of two types:
- Absolute File Paths: It always contains the root element along with the complete directory list required to locate the file.
- Relative File Paths: It is the hierarchical path representation that locates the file or folder on a file system beginning from the current directory.
Example: In this example we embeds the w3wiki logo as a clickable link using the <a> tag, wrapping the <img> tag with the link destination specified in the href attribute.
