I tried this to fix my routing errors. Adding routes after the server is created. This stackoverflow question gave me the inspiration: http://stackoverflow.com/questions/12714999/nodejs-express-redisstore-req-session-undefined It didn't work.

server.js

var express = require('express'),
  path = require('path'),
	http = require('http'),
	wine = require('./routes/wines'),
	cup  = require('./routes/cups'),
	imagepost  = require('./routes/imageposts');
	mongo = require('mongodb'),
	Server = mongo.Server,
	Db = mongo.Db,
	GridStore = mongo.GridStore,
	ObjectID = mongo.ObjectID,
	fs = require('fs'),
	formidable = require('formidable');
	multipart = require('connect-multipart-gridform');
		
var server = new Server('localhost', 27017, {auto_reconnect: true});
var db = new Db('winedb', server, {safe: true});

var app = express();



app.configure(function () {
    app.set('port', process.env.PORT || 3000);
    app.use(express.logger('dev'));  /* 'default', 'short', 'tiny', 'dev' */
	app.use(express.static(path.join(__dirname, 'public')));
	console.log("Before dbopen");
	app.use('/',express.bodyParser());
	db.open(function(err, db) {
	    if(!err) {
	        console.log("Connected to 'winedb' database");
			var multipartoptions = { db: db, mongo: mongo };
			app.use('/imagefiles',multipart(multipartoptions));
			app.get('/imagefiles/:id/data', imagepost.findImageDataById);
			app.post('/imagefiles', imagepost.addImageFile);
	    }
	});
	console.log("after db open");
	//app.use(multipart(multipartoptions),"/imagefiles");
});
