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); 2009/9/25 Damien R <damien.rg@gmail.com>:

also you could try
ar & make_nvp("data", binary_object(sizeof(mpData), & mpData))
This code do not work for dynamic allocation of mpData. data_type * mpData = new data_type[MAX]; sizeof(mpData) = sizeof(data_type *);
but it will be fine if you have static allocation : data_type mpData[MAX]; sizeof(mpData) = MAX * sizeof(data_type);
