Export images of all my doors

Hi all, 

I would like to be able to create automatically an image of all my doors and export it somewhere.

The UI does not support this (the Export\Images and Animations\Images tools do not provide the possibility to choose the range of the export properly).

But the question is rather simple, isn't it? 

I know how to define the geometry (the view, the range that I want to export, etc...). But the problem is to export this range with a simple tool (not the capture tool, though... maybe I could do this ;)

Any simple idea?
