How to Add an Image in HTML: A Step-by-Step Guide
The Basics of Adding Images in HTML
In HTML, images are added using the <img>
tag. This tag is self-closing, meaning it does not require a closing tag.
Basic Syntax of the img Tag
The <img>
tag requires the following attributes:
Attribute | Description | Required |
---|---|---|
src | Specifies the path to the image file | Yes |
alt | Provides alternative text for the image | Yes |
width /height | Optional attributes to define image dimensions | No |
Example:
<img src="example.jpg" alt="Description of the image" width="500">
Adding Images with Different File Paths
Local File
Use a relative path if the image is in the same directory as the HTML file.
<img src="image.jpg" alt="Local image">
Subfolder
If the image is in a subfolder, specify the folder name in the path.
<img src="images/photo.jpg" alt="Subfolder image">
Absolute URL
Use the full URL for images hosted on external servers.
<img src="https://example.com/image.jpg" alt="Remote image">
Responsive Images
To make images responsive (adjustable based on screen size), use CSS or set the width
attribute to 100%
.
Example:
<img src="example.jpg" alt="Responsive image" style="max-width: 100%; height: auto;">

tag to make the image clickable.

<img src="example.jpg" alt="Clickable image" width="300">

attribute empty. Avoid this for informative images.
Example:
<img src="decorative.jpg" alt="" role="presentation">
