retrieving binary data from mongodb to display image in jade template

I have stored image in mongodb without using GriFS.To store image i have used :

var PictureSchema = new mongoose.Schema({
    id :String,
    name :String,
    img: { data: Buffer, contentType: String }
});


var Picture = db.model("Picture", PictureSchema);

app.post("/upload", function (req, res, next) {
    var input = req.body;
    var multiparty=require("multiparty");
    var form=new multiparty.Form();
    form.parse(req,function(err,fields,files){
        var imgE=files.image[0];
        var picture = new Picture;
        picture.id=fields.email[0];
        picture.name=fields.name[0];
        picture.img.data = fs.readFileSync(imgE.path);
        picture.img.contentType = mime.lookup(imgE.path);
        picture.save(function (err, picture) {
          if (err) throw err;
        });
        res.redirect('/view');
    });
});

app.get('/view', function(req, res){
    Picture.find({}, function(err, docs){
        //console.log(docs[0].img);
        if(err) res.json(err);
        else    res.render('index', {pictures: docs});
    });
});

Its stroed data.Now i am not able to fetch this image in jade.I am trying:

ul
each picture in pictures
   li Name: #{picture.name}  
   li Email: #{picture.id}
   br
   div.imagetable
       img(src= "http://" + picture.img)

but its giving "Cannot read property 'img' of undefined"Actually picture object in img tag is getting undefined while i am able to access this object for name and email.

Please help.
