In the very early days of flickr, I wrote this FTPD so that we could have drag and drop uploading via Windows Explorer.
It's non functional because:
- The ingest endpoint does not work
- Flickr doesn't store hashed passwords any more (and they were never hashes like the code now implies anyway)
- There is no SQL escaping
- Probably other issues
It is of historical interest, if any.
You could bring this back in a reasonable way and a 3rd party service by first doing OAuth, then embedding the oauth token in the path portion of the FTP URL. Might be a nice proxy service, although who uses FTP these days?
