To use the <img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/175251709312813.jpeg" class="lazy" alt="How to embed images effectively using the img tag in html?" > tag effectively, always include src and alt attributes. 1. Use src to specify the correct image path and alt for accessibility and SEO. 2. Optimize images by compressing them and choosing the right format — JPEG for photos, PNG for graphics, and WebP for modern browsers. 3. Set proper image dimensions and avoid resizing via HTML. 4. Make images responsive using CSS (width: 100%, height: auto) and the srcset attribute for multiple resolutions. 5. Write descriptive, concise alt text and use meaningful image file names to improve both accessibility and search engine visibility.

When you're working with HTML and want to show images on your page, the <img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/175251709465637.jpeg" class="lazy" alt="How to embed images effectively using the img tag in html?" > tag is your go-to tool. But just slapping an image in there isn't enough — doing it right means making sure your images load fast, look good across devices, and are accessible to everyone. Here’s how to use the <img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/175251709465637.jpeg" class="lazy" alt="How to embed images effectively using the img tag in html?" > tag like a pro.

Use Required Attributes: src and alt

Every <img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/175251709312813.jpeg" class="lazy" alt="How to embed images effectively using the img tag in html?" > tag needs at least two attributes: src and alt.

• src tells the browser where the image file is located. Make sure the path is correct — whether it's a relative path (like /images/photo.jpg) or a full URL.
• alt provides alternative text that appears if the image can't load. It's also crucial for screen readers, helping visually impaired users understand the content.

Example:

<img src="/static/imghw/default1.png"  data-src="dog.jpg"  class="lazy" alt="A golden retriever playing in the grass">

Don’t leave alt empty unless the image is purely decorative — even then, use alt="" so screen readers know to skip it.

Optimize Image Size and Format

Big, high-res images may look great, but they can really slow down your site. Always:

• Compress images before uploading them. Tools like TinyPNG or Squoosh do this well.
• Choose the right format:
  • Use JPEG for photos.
  • Use PNG when you need transparency or sharp graphics (like logos).
  • Consider WebP for modern browsers — it offers better compression than JPEG and PNG.

Also, make sure the image dimensions match what's displayed. Don’t just resize using HTML — that still loads the full file. Resize the image itself before uploading.

Make Images Responsive with HTML and CSS

Images should look good on any screen size. To help with that:

• Set width: 100% and height: auto in your CSS so images scale down smoothly on smaller screens.
• Use the srcset attribute in your <img src="/static/imghw/default1.png" data-src="small.jpg" class="lazy" alt="How to embed images effectively using the img tag in html?" > tag to serve different image sizes based on device pixel density.

Example:

<img src="/static/imghw/default1.png"  data-src="small.jpg"  class="lazy" 
  srcset="medium.jpg 1000w, large.jpg 2000w" 
  alt="Landscape view"
  style="width:100%; height:auto;"
>

This helps mobile users get a lighter image while desktop users see more detail — all without extra work from the user.

Handle Accessibility and SEO Together

The alt attribute plays double duty — it's not only for accessibility but also helps with SEO. Search engines can’t "see" images, so they rely on alt text to understand what an image is about.

Avoid stuffing keywords into alt text. Instead, describe the image clearly and naturally. For example, instead of writing “dog photo picture image,” say “Golden dog running through a field.”

Also, give your image files meaningful names. Instead of IMG_1234.jpg, use something like golden-retriever-playing.jpg. This small change helps both accessibility and search rankings.
