Modify Nodejs-Express-Passport server to upload image automatically - node.js

Question

I am using a nodejs-express-passport solution for authentication with facebook. My goal is to automatically upload an image from a static directory the moment that a user is successfully logged in.
If my image is simply animal.png located at /images how would I modify
the following node-express server code to accomplish this?
var express = require('express');
var passport = require('passport');
var Strategy = require('passport-facebook').Strategy;
passport.use(new Strategy({
clientID: process.env.CLIENT_ID,
clientSecret: process.env.CLIENT_SECRET,
callbackURL: 'http://localhost:3000/login/facebook/return'
},
function(accessToken, refreshToken, profile, cb) {
return cb(null, profile);
}));
passport.serializeUser(function(user, cb) {
cb(null, user);
});
passport.deserializeUser(function(obj, cb) {
cb(null, obj);
});
var app = express();
app.set('views', __dirname + '/views');
app.set('view engine', 'ejs');
app.use(require('cookie-parser')());
app.use(require('body-parser').urlencoded({ extended: true }));
app.use(require('express-session')({ secret: 'keyboard cat', resave: true, saveUninitialized: true }));
app.use(passport.initialize());
app.use(passport.session());
app.get('/',
function(req, res) {
res.render('home', { user: req.user });
});
app.get('/login',
function(req, res){
res.render('login');
});
app.get('/login/facebook',
passport.authenticate('facebook','user_photos'));
app.get('/login/facebook/return',
passport.authenticate('facebook', { failureRedirect: '/login' }),
function(req, res) {
res.redirect('/');
});
app.get('/profile',
require('connect-ensure-login').ensureLoggedIn(),
function(req, res){
res.render('profile', { user: req.user });
});
app.listen(3000);

For res.render('profile', {user: req.user, image: 'my image string location'})
then with your html just pass in {{image}} to wherever you are trying to src the image from.
I am not super familiar with ejs templating but it'd look something like this:
<img src={{image}} alt="MyAnimal.png" style="width:304px;height:228px;">
Or did you want it to just flash on the screen? If that's the case I think you can do something like that with the flash module.
Edit:
I'll move this up here as this was a question for posting desktop data to facebook and not just popping up a picture from the server.
Passport does authentication handshakes to allow people access to your website via login, it does not however open up all the api's to Twitter/Facebook/Google, you'll need to either make them yourself, or use ones that are pre built like this Facebook API.
