Our expert team is currently recording the visual guide for Images and Alt Text.

The Core Concept

Images make your website engaging and easy to read. In HTML, the `<img>` tag displays pictures. Unlike other tags, `<img>` is self-closing—it does not need an ending `</img>` tag. It requires two key attributes: `src` (source, which is the path to your image file) and `alt` (alternative text, which describes the image for screen readers and search engines).

Embed a Developer Profile Photo

Hands-on practice task

Required for Mastery

The Challenge

Write an image tag that embeds a photo named profile.webp located in an images folder. Include an alt text describing it as 'Developer smiling profile photo', and set its display width to 150 pixels.

Helpful Hints

  • Set the src to images/profile.webp.
  • Set the width attribute directly to '150'.

Quick Knowledge Check

Why is my image showing a broken icon?
The path in your src attribute is incorrect. Verify the folder name, spelling, and file extension (like .jpg or .png).
What is the purpose of the alt attribute?
If the image fails to load, or if a user is using a screen reader, the alt text is displayed or read aloud to explain the visual content.
