User always like to keep good images in their phone. so, In that condition user should have an app that can provide facility of save images also. This blog simply shows how you can write code that would allow user to save Image locally in their Save Image Photo album.

Here, you can see some piece of code which containing a function SaveImageToPhotoHub with few statements and a parameter type WriteableBitmap. This SaveImageToPhotoHub function returns either true or false output. To work with this function you just need to pass needed Image as parameter in SaveImageToPhotoHub function.

 private bool SaveImageToPhotoHub(WriteableBitmap bmp)

            using (var mediaLibrary = new MediaLibrary())
                using (var stream = new MemoryStream())
                    var fileName = string.Format("Gs{0}.jpg", Guid.NewGuid());
                    bmp.SaveJpeg(stream, bmp.PixelWidth, bmp.PixelHeight, 0, 100);
                    stream.Seek(0, SeekOrigin.Begin);
                    var picture = mediaLibrary.SavePicture(fileName, stream);
                    if (picture.Name.Contains(fileName)) return true;
            return false;

WriteableBitmap provides a BitmapSource that can be written to and updated. To declare WritableBitmap class you must include System.Windows.Media.Imaging namespace

using System.Windows.Media.Imaging;

MediaLibrary is a class which is used to access songs, playlists, and pictures in the device’s media library. To acess MediaLibrary class you need to include Microsoft.Xna.Framework.Media namespace

using Microsoft.Xna.Framework.Media;

SaveJpeg is an Extentions method which is responsible to encodes a WriteableBitmap object into a JPEG stream, with parameters for setting the target width and height of the JPEG file.

SavePicture is a method of MediaLibrary class which saves the image contained in the stream object to the media library, and then returns that saved image as a picture object.

To acess MemoryStream class you need to include System.IO namespace.

using System.IO;

Now take a look how to use the above method for saving image.

private void Save_Click(object sender, EventArgs e)
            WriteableBitmap bmp = new WriteableBitmap(imgview, null);
            if (SaveImageToPhotoHub(bmp))
                MessageBox.Show("Image Saved", "Information", MessageBoxButton.OK);
                MessageBox.Show("Error : Image Not Saved", "Information", MessageBoxButton.OK);

Here, imgView is an Image Control which is placed in xaml part

Note :- To run this code properly your app should have capabilities to access Windows Phone windows phone media library hub. You can simply do this by checking ID_CAP_MEDIALIB_PHOTO from capabilities tab of WMAppManifest.xml
