DBImage i obrazki w c++ Builder

Witam,
Mam problem z wczytaniem obrazka jpg do DBImage. Oto moj kod:

        if(OpenPictureDialog1->Execute())
        { if(!FileExists(OpenPictureDialog1->FileName))
            return;
          else
        {   AnsiString tmp=ExtractFileName(OpenPictureDialog1->FileName);
            AnsiString tmp2=ExtractFileExt(OpenPictureDialog1->FileName);
            AnsiString Ext=tmp2.LowerCase();


            if(Ext.AnsiPos("jpg")>0)
            { TJPEGImage *myjpeg=new TJPEGImage();
              myjpeg->LoadFromFile(OpenPictureDialog1->FileName);
              myjpeg->DIBNeeded();

              DBImage1->Assign(myjpeg);
              delete myjpeg;

        }
        }
        }

Niestety nie mozna zrobic assign'a w ten sposob, bo pojawia sie niezgodnosc typow. Prosilbym o wskazowki w jaki sposob mozna rozwiazac ten problem.
Pozdrawiam.
