[Paraview] using paraview 3.2.1 in batch mode to produce a collection of jpg's

[fer Mellibovsky]

I have a collection of vtk files from which to make a picture. I have 
loaded into paraview 3.2.1 one of them and drawn some contour levels. I 
wanted to save the result as a pvb file in order to run a script using 
pvbatch to produce the whole series of jpg, but this option no longer 
exists. What can I do. Is there a way to load a pvsm file in batch mode 
and produce a jpg?
Thank you
