Images

The Cloudflare Images binding (env.IMAGES) is available in celld with partial behavior. Transforms run locally in the celld process (Rust image crate)—celld does not call Cloudflare’s remote Images API. cellp does not add a Dashboard or operator API; declare and deploy like any other wrangler binding.

What works

Typical resize / format pipeline:

const out = await env.IMAGES
  .input(imageBytes)
  .transform({ width: 800, fit: 'scale-down' })
  .output({ format: 'webp', quality: 85 })
return out.response()

input() accepts ReadableStream, ArrayBuffer, views, Blob, or Response. transform() supports width, height, fit, gravity, background, rotate (multiples of 90), flip, flop. output() supports jpeg, png, webp, avif with quality on jpeg/webp.

What does not

• No call to Cloudflare’s remote Images API or billing.
• Many transform options (blur, sharpen, trim, border, overlays / draw()) fail closed.
• Inputs larger than 32 MiB are refused.

Images do not branch across preview child versions as a managed dataset (same pattern as Worker script: this version’s runtime only).
