This skill should be used when the user asks to "upload images to Cloudflare", "implement direct creator upload", "configure image transformations", "optimize WebP/AVIF", "create image variants", "generate signed URLs", "add image watermarks", "integrate with Next.js/Remix", "configure webhooks", "debug CORS errors", "troubleshoot error 5408/9401-9413", or "build responsive images with Cloudflare Images API".

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Cloudflare Images

**Status**: Production Ready ✅ | **Version**: 3.0.0 | **Last Verified**: 2025-12-27

## What Is Cloudflare Images?

Two powerful features:

1. **Images API**: Upload, store, serve images globally
2. **Image Transformations**: Resize/optimize ANY image

**Key benefits:**
- Global CDN delivery
- Automatic WebP/AVIF conversion
- Up to 100 variants
- Direct creator upload (no API keys in frontend)
- Signed URLs for private images
- Transform any image via URL or Workers

---

## Quick Start (5 Minutes)

### 1. Enable Cloudflare Images

Dashboard → **Images** → **Enable**

Get your **Account ID** and create **API token** (Cloudflare Images: Edit permission)

### 2. Upload Image

```bash
curl --request POST \
  --url https://api.cloudflare.com/client/v4/accounts/<ACCOUNT_ID>/images/v1 \
  --header 'Authorization: Bearer <API_TOKEN>' \
  --header 'Content-Type: multipart/form-data' \
  --form 'file=@./image.jpg'
```

**CRITICAL:** Use `multipart/form-data`, not JSON

### 3. Serve Image

```html
<img src="https://imagedelivery.net/<ACCOUNT_HASH>/<IMAGE_ID>/public" />
```

### 4. Enable Transformations

How to install

The exact contents, by fingerprint
mdr add secondsky/claude-skills/cloudflare-images@sha256:1e9299f9362e27b4

The line at the top of this page pins the label v3.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
