Comment (by Jan Vonasek <jan.vonasek@…>):

 Sample code:
 std::wstring sInput = cca 20kB text (HTML template containing texts like
 "ImagePath1", "ImagePath2",...);
 std::wstring sFormat1 = cca 300kB text (base64 encoded image);
 boost::replace_all(sInput, L"ImagePath1", sFormat1);
 std::wstring sFormat2 = cca 300kB text (base64 encoded image);
 boost::replace_all(sInput, L"ImagePath2", sFormat2);
