Gheorghe,

	You are not describing the steps you followed. Have you read the online 
documentation for vtkImageViewer ?

http://www.vtk.org/doc/nightly/html/classvtkImageViewer.html

	Have look at the tests/examples associated with vtkImageViewer ? Do 
they miss something you are trying to achieve ?

http://www.vtk.org/doc/nightly/html/c2_vtk_e_2.html#c2_vtk_e_vtkImageViewer
http://www.vtk.org/doc/nightly/html/c2_vtk_t_7.html#c2_vtk_t_vtkImageViewer

	You seems to be using VTK+Tk+Python. Have you played with the examples 
in VTK/Wrapping/vtk/tk. Do they work for you ? What are they missing ?

	If you see a problem, please post a simple code to reproduce. In your 
case, a simple python+tk script that demonstrate the problem is fine 
(use Data from VTKData is possible). Do not forget to specify the 
version of VTK you are using.

Thanks
Mathieu
