What are Images in HTML?

Images are visual elements used to enhance the content of a webpage, making it more attractive, engaging, and informative. In HTML, images are added using the <img> tag, which is a self-closing (empty) tag. The <img> tag requires attributes such as src to specify the image source and alt to provide alternative text for accessibility. Additional attributes like width, height, title, srcset, and loading allow developers to control size, responsiveness, performance, and user interaction, making images an integral part of modern web design.

Basic Image Tag in HTML

Syntax:

<img src="image.jpg" alt="Description of image">

src → Path of the image file.
alt → Alternate text shown if the image doesn’t load (important for SEO and accessibility).

Example:

<img src="nature.jpg" alt="Beautiful Nature Image">

Example with additional attributes:

<img src="nature.jpg" alt="Beautiful Nature" width="400" height="300" title="Nature Image">

How Images Are Added

Local Images

Images stored within your project folder.
Best practice: keep images in a dedicated folder like images or assets.

Example :

<img src="images/photo.jpg" alt="Local Image Example">

External Images

Images loaded directly from the internet using a full URL.
Useful when using images from CDNs, stock photos, or external websites.

Example :

<img src="https://www.example.com/image.jpg" alt="External Image Example">
