woodtableguy888 — Image Upload Worker

A Cloudflare Worker that fetches images from a remote URL and stores them directly into an R2 bucket, streaming the response body without buffering.

How it works

1. Receives a POST request with a JSON body containing a source URL and a destination path
2. Checks if the file already exists in R2 — skips if so
3. Fetches the image from the source URL (with optional Referer header)
4. Streams the image body directly into R2 without loading it into memory
