</head>
<body>
<h1 id="Welcome-to-My-Page">Welcome to My Page</h1>

The ![How do you add images to your HTML page using the <img> tag?]("path/to/your/image.jpg")
- src: This attribute specifies the path to the image file. It can be a relative path (e.g.,
"/images/photo.jpg") or an absolute URL (e.g.,"https://example.com/images/photo.jpg"). - alt: This attribute provides an alternative text description of the image. It is crucial for accessibility and is displayed if the image cannot be loaded. It also helps with SEO.
Other important attributes include:
- width and height: These attributes specify the dimensions of the image. Including them can help the browser allocate space for the image before it loads, improving the page's perceived load time.
- loading: This attribute can be set to
"lazy"to defer the loading of off-screen images until they're needed, which can improve page load times.

<img src="/static/imghw/default1.png" data-src="path/to/your/image.jpg" class="lazy" alt="Description of image" style="max-width:90%" style="max-width:90%" loading="lazy">
