In case it doesn't exist yet:

A switch that prevents POV-Ray to overwrite an existing scene image with
a new one. Instead, POV-Ray would attach a dash and a number to the
image name and create that way a new image.  Also checking if that
particular image number exists already, then simply incrementing the
highest found image number by one. This way, the various renders of the
same scene will create over time a series of images, not losing the
existing ones.

This switch would save me (and many others) the additional work of
having first to rename an existing scene image before rendering the same
scene again. Great also for comparisons.

iiuc, you can already do this.

see section 3.2.6 of the docs, the 'Post_*_Command's.

you know your scene's file name and have access to the frame number,
so writing a batch file to do the copy should be trivial.

Hi, thanks for your answer, well appreciated. I am going to read that
section in a few minutes. But you also speak about "Frames". This is not
an animation I am talking about. Anyway, please give me a few minutes to
read that section. :-)
