This is a nodejs question concerning couchdb attachments.  It seems too =
specific to post on stack overflow.  I have 2 very long days into this =
so any help is deeply appreciated!

I am trying to connect a write stream from graphicsmagic to a readstream =
in cradle in order to send a document I processed with graphics magic to =
couchdb.=20

/* this makes the files, but loops infinitely */
									=
im(result.buffer, v.name)
									=
.resize(s.width, s.height)
									=
.autoOrient()
									=
.write("./temp/" + s.width + 'x' + s.height + v.name, function (err) { =
// <-- this is the write stream
									 =
	if (!err) {
										=
	var attachmentData =3D {
										=
	  name: s.width + 'x' + s.height + v.name,
										=
	  'Content-Type': v.type,
										=
	  body: fs.readFileSync("./temp/" + s.width + 'x' + s.height + =
v.name) // <-- this is the read stream
										=
	};
										=
	db.saveAttachment(docId, attachmentData, function (err, reply) {
										=
	  if (err) {
										=
	    console.log(err)
										=
	    return
										=
	  }
										=
	  console.log(reply)
										=
	});
										=
}
									=
});

Theses are the docs I am pulling from:

https://github.com/aheckmann/gm
https://github.com/cloudhead/cradle

Is anyone doing this?  Maybe doing it another way?  I don't care whether =
I use cradle or not just that I send the processed attachment to couch.
