[vtkusers] vtkTIFFReader Examples + Data

[Dominik Szczerba]

i would suggest you convert the tiffs to another format and try e.g. 
PNGReader. I used to have problems with tiffs. another debugging would 
be to try to load your data into the latest paraview to see if the 
problem is there too (uses VTK CVS version)
