When a user taps a pin the app fetches photos from Flickr for that location and then the user can add top and bottom captions and then share the updated photo. Implementation MapViewController.swift which manage the pins. ShareImageViewController.swift which allows the users to add top and bottom captions and then share the updated photo ImagesViewController.swift which manage the photos fetched by flicker and display them in collection view.
