Responsive Image Delivery with Art Direction

Responsive image delivery is essential for optimizing web performance and user experience across various devices. This lesson delves into techniques for delivering images responsively with a focus on art direction—ensuring that the right image is served for the right context.

• Responsive Images: Images that adapt to different screen sizes and resolutions.
• Art Direction: Choosing different images or crops based on the viewing context.
• HTML Attributes: Understanding srcset and sizes attributes for responsive images.

Art direction involves not just scaling images, but selecting different images or compositions based on the viewport size. This is particularly useful for images that carry significant visual weight or storytelling elements.

Example Implementation

<picture>
    <source media="(min-width: 800px)" srcset="large-image.jpg">
    <source media="(min-width: 400px)" srcset="medium-image.jpg">
    <img src="small-image.jpg" alt="Description of image">
</picture>
            

1. Use the <picture> Element

Utilizing the <picture> element enables art direction effectively.

2. Optimize Images

Always serve optimized images in terms of file size and format (e.g., WebP, JPEG, PNG).

3. Use srcset and sizes Attributes

Make sure to provide a srcset containing multiple resolutions for better performance.

4. Test on Multiple Devices

Ensure images look good on various screen sizes and resolutions.
