The <img> element serves as a specialized HTML tag designed specifically for inserting images into a webpage. It has been a fundamental component of web development since the inception of the internet and continues to play a crucial role in crafting visually appealing and informative websites.
Syntax:
<img src = "https://placehold.co/400x300/1abc9c/ffffff?text=Sample+Image" alt = " Description of the picture ">
The source URL of the image is specified by the src attribute, while the alt attribute provides alternative text for accessibility and SEO purposes. It is important to identify and isolate the key components of the <img> element.
1. Source (src) Attribute
The src attribute plays a crucial role in the <img> element by specifying the URL where the image file is located for display on the webpage. The file can either be stored locally or sourced from a remote location on the internet.
For example:
<img src = "https://placehold.co/400x300/1abc9c/ffffff?text=Sample+Image" alt = " Local Image ">
<img src = "https://placehold.co/400x300/1abc9c/ffffff?text=Sample+Image" alt = " Remote Image ">
2. Alternative Text (alt) Attribute
The alt attribute provides alternative text displayed when an image fails to load, serving as a crucial accessibility feature that enables screen readers to convey the image content to users with visual impairments.
For example:
<img src = "https://placehold.co/400x300/1abc9c/ffffff?text=Sample+Image" alt = " A beautiful sunset over the mountains ">
Example:
<!DOCTYPE html>
<html lang = " en ">
<head>
<meta charset = " UTF-8 ">
<meta name = " viewport " content = " width = device-width, initial-scale = 1.0">
<title> Simple Image Example </title>
</head>
<body>
<h1> Simple Image Example </h1>
<!-- Basic Usage -->
<img src = "https://placehold.co/400x300/1abc9c/ffffff?text=Sample+Image" alt = " An example image ">

Advanced Attributes
Even though the src and alt attributes are essential, the <img> element introduces various attributes that provide enhanced control and customization.
- Dimensions: The width and height attributes enable developers to specify the dimensions of the image, granting authority over the layout and avoiding unexpected shifts in page content upon image loading.
For Example:
Utilizing srcset for Responsive Images: When designing a responsive website, the srcset attribute allows the browser to select the most suitable image source based on the user's device characteristics, such as screen size and resolution.
For Example:
Implementing Lazy Loading: Lazy loading can be achieved by using the loading attribute, which allows developers to delay the loading of images that are not currently visible on the screen until they are about to be displayed in the viewport.
For Example:
<img src = "https://placehold.co/400x300/1abc9c/ffffff?text=Sample+Image" alt = " Lazy Loaded Image " loading = "lazy">
