The File access sample shows you how to use the PicturesLibrary property to create a new file in the Pictures library.

StorageFolder storageFolder = KnownFolders.PicturesLibrary;
StorageFile file = await storageFolder.CreateFileAsync("sample.png", CreationCollisionOption.ReplaceExisting);
// Do something with the new file.
Windows.Storage.KnownFolders.picturesLibrary.createFileAsync("sample.png", Windows.Storage.CreationCollisionOption.replaceExisting).done(
   function (file) {
       // Process file
   // Handle errors with an error function
   function (error) {
       // Process errors

After the CreateFileAsync method completes, the file variable contains a StorageFile that represents the new file.
