Correctly incorporating images into your HTML code can greatly enhance the user experience of your website, making it more engaging and interactive. W3Schools, a popular resource for web developers, provides clear guidelines and examples for using the <img> tag to insert images into your HTML content. Let's dive into the etiquette of using <img> in HTML, following W3Schools' recommendations.
At the core of using <img> is the understanding that it's an empty tag, meaning it doesn't have a closing tag like </img>. Instead, you must close it by inserting a forward slash (/) before the second identical symbol (i.e., >). Here's the basic syntax:
The Basic <img> Syntax
The fundamental structure of the <img> tag includes the src (source) attribute, which specifies the image source file, and the alt (alternative) attribute, providing a text description for accessibility purposes:
<img src="url" alt="description">
Image Source (src)
The src attribute is mandatory and refers to the image file's location. It can be either a relative URL (pointing to the same domain) or an absolute URL (pointing anywhere on the web).
Example: <img src="https://www.example.com/images/pic.jpg" alt="A nice image">
Alt Text (alt)
Alt text is displayed when an image can't be rendered, improving accessibility for visually impaired users and search engine understanding of the image's content.
Best practice is to keep alt text concise yet descriptive. Avoid using it as a placeholder for text you intend to display visually.
Additional <img> Attributes
Beyond src and alt, W3Schoolsrecommends using other attributes sparingly, as they can complicate your code and reduce accessibility:
Width and Height
The width and height attributes specify the dimensions of an image. Including these values helps browsers to render webpages faster by allocating space for the image before it loads.
Example: <img src="image.jpg" alt="Image description" width="300" height="200">
Align
The align attribute positions images in relation to surrounding text. However, for better control over image placement, consider CSS instead of this deprecated attribute.
Example: <img src="image.jpg" alt="Image description" align="right">
Remember, while these additional attributes are allowed, using them sparingly to maintain clean, accessible HTML is good practice. Always prioritize the fundamental src and alt attributes when using the <img> tag in your HTML.

Including images in your HTML layout can significantly improve user experience and engagement. By following W3Schools' best practices for the <img> tag, you can create more accessible, visually appealing, and SEO-friendly web content—so take the time to incorporate these principles into your coding workflow.
