[vtkusers] Multiple Image in one screen ((Dicom images))

[Hellice]

Hi
The vtk is realy big and am jumping here and there try to get out with
somthing useful;
I am now trying to display Dicom  images on 2D  in one windows 

It's simple :
1- I created An array of actors withe max 200
2- read my set of data Dicom with vtkdicomimagereader
3-mappe it on mapper with vtkimagemapper
4- for eache slice iset the position of an actor than i set this actor withe
the mapper data ((Act[slicenumb]->setMapper(MapImag) )) and befor that i did
MapImage->Setzslice(slicenumb)]
5- Update the mapper and add eache actore to the render
6- do the usuale stuff to render  every thing

The probleme is the actors i created get only the laste slice imageand i get
window with one image Duplicate Number of slice time Like that
http://vtk.1045678.n5.nabble.com/file/n5590677/Untitled_5.jpg 
and i dont want that 

here is my mane
*******************************************
*
int main()
{

	vtkActor2D *Actors[500];

	vtkDICOMImageReader *reader = vtkDICOMImageReader::New();
	vtkImageActor *viewer = vtkImageActor::New();
    reader->SetDirectoryName("Data1");
	reader->Update();

	vtkImageResample *resiz = vtkImageResample::New();
	resiz->SetInputConnection(reader->GetOutputPort());
	resiz->SetAxisMagnificationFactor(0,0.3);
	resiz->SetAxisMagnificationFactor(1,0.3);



	vtkImageMapper *ImageMap = vtkImageMapper::New();
	ImageMap->SetInputConnection(resiz->GetOutputPort());
    vtkRenderer *ren1= vtkRenderer::New();
    vtkRenderWindow *renWin = vtkRenderWindow::New();
	int slices = ImageMap->GetWholeZMax();

	Actors[0] = vtkActor2D::New();
    Actors[0]->SetMapper(ImageMap);
	ren1->AddActor2D(Actors[0]);
	renWin->AddRenderer( ren1 );

	for(int i=1;i<slices;i++)
	{
	   ImageMap->SetZSlice(i);
       Actors[i] = vtkActor2D::New();
	  
Actors[i]->SetPosition(Actors[i-1]->GetPosition()[0]+65,Actors[i-1]->GetPosition()[1]);
       if(Actors[i]->GetPosition()[0]>=600)
	   {
		   Actors[i]->SetPosition(0,Actors[i-1]->GetPosition()[1]+65);
	   }

	   Actors[i]->SetMapper(ImageMap);     
	   
	   ImageMap->Update();
	   ren1->AddActor2D(Actors[i]);
	   renWin->AddRenderer( ren1 );
 
	}



  
  ren1->SetBackground( 0.1, 0.2, 0.4 );
  
  
  renWin->SetSize( 600, 600 );

  vtkRenderWindowInteractor *iren = vtkRenderWindowInteractor::New();
  iren->SetRenderWindow(renWin);
  iren->Initialize();
  iren->Start();


}
*

And also the intractore does nothing bcoze this is importan to any medicale
softeware
