In Windows Phone 8.1 XAML apps you can use the FileOpenPicker to select am image either from the picture library, or from the camera. Make sure you have added ".jpg" to the picker file types, otherwise the camera button may not show. Here is sample code:

FileOpenPicker picker = new FileOpenPicker();
picker.FileTypeFilter.Add(".png");
picker.FileTypeFilter.Add(".jpg");

picker.ContinuationData["DATA"] = "MYDATA";  // The app may be closed while displaying the picker dialog, and this data will be passed back to the application on activation.

picker.PickSingleFileAndContinue();
