var busboy = require('connect-busboy');

//... 

router.route('/images')  
    .post (function(req, res) { 

    var fstream; 
    req.pipe(req.busboy); 
    req.busboy.on('file', function (fieldname, file, filename) { 
     console.log("Uploading: " + (fieldname)); 
     fstream = fs.createWriteStream(__dirname + '/public/img/'+ filename); 
     file.pipe(fstream); 
     fstream.on('close', function() { 
     res.status(200); 
     res.json({ message: 'File uploaded' });
