within ImageViewController, use the place_id to download an array, use
FLICKR_RESULTS_PHOTOS to allocated the array. then use IndexPath.row to
select a 'self.photos' dictonary within this array.
    Then use [FlickrFetcher URLforPhoto:self.photos
format:FlickrPhotoFormatLarge] to find URL for certain image. start
another download task to download the image using function UIImage
*image = [UIImage imageWithData:[NSData
dataWithContentsOfURL:location]]; Next step is doing recent 20 photos.
