Florent,

 vtkBMPReader *imagein=vtkBMPReader::New();
  imagein->SetFilePrefix ("slices"); // name of the files to read
  imagein->SetDataExtent(0, 255, 0, 255,0,5);
  imagein->Update();

 double* range = imagein->GetOutput()->GetScalarRange();
 
 What are range[0] and range[1] ? 

 What happens if you try an iso-contour value of 101?
 What happens if you try an iso-contour value of 99?
 What happens if you try an iso-contour value of 254?
