Thanks all of you for your ideas and suggestions
I finally realized the serialize(archive& ar, const unsigned) funktion using
            ar & make_nvp("data", make_binary_object(mpData, mWidth*mHeight);
but I have to say that the memory behind mpData bust be allocated
first on reading an image.
Finaly I endet up with

template<class archive>
void serialize(archive& ar, const unsigned int version) {
  using boost::serialization::make_nvp;
  using boost::serialization::make_binary_object;
  if (archive::is_saving::value) {
    ar & make_nvp("width", mWidth);
    ar & make_nvp("height", mHeight);
    ar & make_nvp("data", make_binary_object(mpData, mWidth*mHeight);
  } else if (archive::is_loading::value)
    int w, h;{
    ar & make_nvp("width", w);
    ar & make_nvp("height", h);
