HTML <img> Tag

What is HTML <img> Tag?

The HTML img tag is used to embed images into a webpage. It allows you to display pictures, logos, illustrations, or any visual content directly on a web page. The img tag helps make web content more attractive and engaging.

It is one of the most important tags in HTML because visual content improves user experience and helps in communicating ideas quickly. The img tag is an empty tag, which means it does not have a closing tag. It only contains attributes that define the source, size, and description of the image.

Every website uses the HTML img tag to make content more appealing. It can be used for logos, banners, backgrounds, and product photos. Search engines also read the alt text inside the img tag to understand what the image represents, which improves SEO.

Syntax of the HTML <img> Tag

plaintext
<img src="image.jpg" alt="description">

The src attribute specifies the image file path, while alt provides alternative text for accessibility and SEO.

Examples of HTML <img> Tag

Example 1: Basic HTML Image Tag

plaintext
<!DOCTYPE html>
<html lang="en">
<body>

  <img src="logo.jpg" alt="Scholar247 Logo">

</body>
</html>

In this example, the img tag displays a simple image named "logo.jpg" on the webpage. The alt text "Scholar247 Logo" is used to describe the image, which helps users and search engines understand the content if the image fails to load.

Example 2: SEO Optimized Image Tag

plaintext
<!DOCTYPE html>
<html lang="en">
<body>

  <img src="web-development-services.jpg" alt="Best Web Development Services by Scholar247" width="600" height="400">

</body>
</html>

This example demonstrates an SEO-friendly image tag. It uses descriptive alt text that includes the keyword “Best Web Development Services by Scholar247,” making the image more discoverable in search results. The width and height attributes ensure proper loading and layout stability.

Attributes of the HTML <img> Tag

The HTML img tag supports several attributes that help control how the image appears and behaves on a webpage:

• src: Specifies the path or URL of the image file.
• alt: Provides descriptive text if the image fails to load. It also improves SEO.
• width: Defines the width of the image in pixels or percentage.
• height: Defines the height of the image in pixels or percentage.
• title: Displays extra information about the image when a user hovers over it.
• loading: Determines how the image is loaded. The “lazy” value delays loading until the image is visible.

Best Practices for HTML <img> Tag

• Always include descriptive alt text for accessibility and SEO.
• Use compressed image formats like WebP or JPEG for faster loading.
• Specify width and height to prevent layout shifts during page loading.
• Use responsive image attributes for better display on different devices.
• Keep image filenames descriptive and keyword-rich for better SEO ranking.
• Avoid using large image sizes that slow down your page performance.
