HTML Prototypes tips

💻

Copy the data URL and use it as <img src="data:image/png;base64,..."> — no external file needed.

💡

For fast prototyping, this beats fetching from placeholder.com or unsplash — no external network requests in your dev environment.

🎯

For real production, replace with optimized real images. Data URLs add to HTML size and aren't cacheable separately.
