title: Save image to phone storage
body: <p>I have image control and I want to save this image to phone storage.
  So, I have Image control and below button. When user click the button, image should be saved to phone storage.
  How can I do this ?</p>
  
  <p>I found code:</p>
  
  <pre><code> // Create a file name for the JPEG file in isolated storage.
          String tempJPEG = "TempJPEG";
  
          // Create a virtual store and file stream. Check for duplicate tempJPEG files.
          var myStore = IsolatedStorageFile.GetUserStoreForApplication();
          if (myStore.FileExists(tempJPEG))
          {
              myStore.DeleteFile(tempJPEG);
          }
  
          IsolatedStorageFileStream myFileStream = myStore.CreateFile(tempJPEG);
  
  
          // Create a stream out of the sample JPEG file.
          // For [Application Name] in the URI, use the project name that you entered 
          // in the previous steps. Also, TestImage.jpg is an example;
          // you must enter your JPEG file name if it is different.
          StreamResourceInfo sri = null;
          Uri uri = new Uri("[Application Name];component/TestImage.jpg", UriKind.Relative);
          sri = Application.GetResourceStream(uri);
  
          // Create a new WriteableBitmap object and set it to the JPEG stream.
          BitmapImage bitmap = new BitmapImage();
          bitmap.CreateOptions = BitmapCreateOptions.None;
          bitmap.SetSource(sri.Stream);
          WriteableBitmap wb = new WriteableBitmap(bitmap);
  
          // Encode the WriteableBitmap object to a JPEG stream.
          wb.SaveJpeg(myFileStream, wb.PixelWidth, wb.PixelHeight, 0, 85);
          myFileStream.Close();
  
          // Create a new stream from isolated storage, and save the JPEG file to the media library on Windows Phone.
          myFileStream = myStore.OpenFile(tempJPEG, FileMode.Open, FileAccess.Read);
  
          // Save the image to the camera roll or saved pictures album.
          MediaLibrary library = new MediaLibrary();
  
  
          Picture pic = library.SavePicture("SavedPicture.jpg", myFileStream);
          MessageBox.Show("Image saved to saved pictures album");
  
  
          myFileStream.Close();
  </code></pre>
