Image from server to LocalFile in Windows Phone 8.1

I am writing a Windows Phone 8.1 (WINRT) App.

I am getting the url of image from server. I want to save the image from this url to localstorage file.

string PictureUrlFromServer= "http://www.server.com/images/abc.png";

I wrote this:

StorageFolder StorageFolderObject = await Windows.Storage.ApplicationData.Current.LocalFolder.CreateFolderAsync(LocalCache, CreationCollisionOption.OpenIfExists);
            StorageFile StorageFileObject = await StorageFolderObject.CreateFileAsync(LocalProfilePicName, CreationCollisionOption.ReplaceExisting);

After it what to do?

EDIT:

I even tried using below code, but its not working:

StorageFolder StorageFolderObject = await Windows.Storage.ApplicationData.Current.LocalFolder.CreateFolderAsync(LocalCache, CreationCollisionOption.OpenIfExists);
        StorageFile StorageFileObject = await StorageFolderObject.CreateFileAsync(LocalProfilePicName, CreationCollisionOption.ReplaceExisting);

        HttpClient HttpClientObject = new HttpClient();

        HttpClientObject.DefaultRequestHeaders.Add("user-agent", "Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)");
        Uri UriObject = new Uri(_BitmapImageUriSource);
        HttpResponseMessage HttpResponseMessageObject = await HttpClientObject.GetAsync(UriObject);
        HttpResponseMessageObject.EnsureSuccessStatusCode();
        var responseBuffer = await HttpResponseMessageObject.Content.ReadAsBufferAsync();

        await Windows.Storage.FileIO.WriteBufferAsync(StorageFileObject, responseBuffer);

Error: Access denied on StorageFileObject

To download file from web, you can use HttpClient. 

HttpClient client = new HttpClient(); // Create HttpClient
byte[] buffer = await client.GetByteArrayAsync(PictureUrlFromServer); // Download file

StorageFile file = await ApplicationData.Current.LocalFolder.CreateFileAsync("Image.png", CreationCollisionOption.ReplaceExisting); // Create local file
using (Stream stream = await file.OpenStreamForWriteAsync())
    stream.Write(buffer, 0, buffer.Length); // Save
