HTML Images

Images are an essential component of web design. They enhance visual appeal, convey information, and improve user experience. In HTML, the <img> tag is used to embed images into a webpage. This tag is empty, meaning it only contains attributes and does not have a closing tag.

Basic Syntax

The <img> tag is a self-closing tag, meaning it doesn’t require a closing tag. It has several attributes to control the image’s display and behavior.

<img src="url" alt="description">

Attributes:

    • src: Specifies the path to the image file.
    • alt: Provides alternative text for the image, used by screen readers and displayed if the image fails to load.
    • width: Sets the width of the image in pixels.
    • height: Sets the height of the image in pixels.
    • title: Specifies additional text that appears when the mouse hovers over the image.

    Example

    Here’s a simple example of an image embedded in an HTML page:

    <!DOCTYPE html>
<html>
<head>
  <title>HTML Images</title>
</head>
<body>

  <img src="image.jpg" alt="A beautiful landscape" width="300" height="200" title="Click to enlarge">

</body>
</html>

    In this example:

    • image.jpg is the name of the image file.
    • “A beautiful landscape” is the alternative text.
    • The image will be displayed with a width of 300 pixels and a height of 200 pixels.
    • When hovering over the image, the text “Click to enlarge” will appear.

    Image Optimization

    To improve website performance, it’s essential to optimize images:

    • Resize images: Make sure images are the appropriate size for your webpage.
    • Compress images: Reduce file size without compromising quality.
    • Use appropriate format: Choose the best format for your image type.
    • Consider image lazy loading: Defer loading images until they are needed.

    Additional Tips

    • Provide meaningful alt text: Descriptive alt text improves accessibility and SEO.
    • Use relative paths: Specify image paths relative to the HTML file for better portability.
    • Consider responsiveness: Make images responsive to different screen sizes using CSS.

    Conclusion

    Images are a powerful tool for enhancing web content. By understanding the <img> tag and its attributes, you can effectively incorporate images into your web pages. Remember to optimize images for performance and accessibility.
