You can't save or modify a BitmapImage. You need to use a WriteableBitmap instead. If you really have no choice but start with a BitmapImage - check its UriSource property to either download the same image again or load a WriteableBitmap with same content as the starting BitmapImage. Note that UriSource might be null in some cases - even if the BitmapImage was loaded by giving it a URI - it might be reset manually or by setting CacheMode to BitmapCache on an Image that's using the given BitmapImage as its Source.
