TImage does not have any tiling option. You should get rid of the
TImage altogether and draw the .bmp directly onto the TForm's Canvas
in its OnPaint event. Then you can draw it any way you wish. For
example:

private:
Graphics::TBitmap *FBmp;

__fastcall TForm1::TForm1(TComponent *Owner)
{
FBmp = new Graphics::TBitmap;
FBmp->LoadFromFile("myimage.bmp");
}

void __fastcall TForm1::FormPaint(TObject *Sender)
{
for(int y = 0; y < ClientHeight; y += FBmp->Height)
{
for(int x = 0; x < ClientWidth; x += FBmp->Width)
Canvas->Draw(x, y, FBmp);
}
}

The same way as I showed you earlier. Just use a TJPEGImage instead
of a TBitmap. They both derive from TGraphic, which is what
TCanvas::Draw() takes as an input parameter.
