Every image below is fetched live from Cloudflare R2 through a Worker binding. No CDN tricks, no signed URLs, no API calls — just env.BUCKET.get(key).
env.BUCKET.get("images/sample-1.jpg") — a native Cloudflare binding, not an external API call, not an S3 SDK request. R2 returned the bytes; the Worker streamed them to you with the right Content-Type header. No signing, no auth tokens to manage, no SDK to install.
