I uploaded image to the server, but failed to bring images

-mean -----server --------- config -------------config.js -------- controllers -------- data -------- images <---I saved images here using "multer "package

I added this line in mean/server/config/config,js

• app.use('images', express.static(path.join(__dirname,'/../images')))

When I try to access a static image from the browser=>localhost:4040/images it gives me 401 Unauthorized error.

I don't know why it does not work. Could you please able to give me an advice?
