위에 jpeg.hpp인클루드도 시켜줬고
머때문에 그런지 몰르겠어여


        pStream = pQuery->CreateBlobStream(pField, bmRead);
        if(pStream->Size > 0)
        {
          pJPEG = new TJPEGImage();
          pJPEG->LoadFromStream(pStream);
          pBMP->Assign(pJPEG);
          imgDisplay->Picture->Assign(pJPEG);
          delete pJPEG;
          pJPEG = NULL;
        }
        else imgDisplay->Picture->Assign(NULL);
        delete pBMP;
        delete pStream;

부탁드립니다..
