i am a new bird to use pov-ray for windows,meet a problem about save the
result.
   i want to save images that are created by the same scene below different
camera.but i just find the last image,not all.

The image has the same name as the file that is used to create it, unless:
-you use the animation feature by setting the final_frame in the command 
line and then using frame_number in the scene to decide which camera to 
display. In this case the files are numbered by the frame number.
Example:
#if(frame_number==n)
  camera{
   ...
  }
#end
-you set output_file in the command line, which overrides the automatic 
naming completely. In this case you select the camera to be rendered 
manually.
-the newest beta has a real-time camera animating feature that renders 
all the cameras one after another. However, I don't know whether this 
feature saves any of these images.

Unless you use the last option specified (I assume you use v3.6 - which 
you should) Povray always renders the last camera added to the scene.

the command line options are typed in the text box next to where you 
select the output resolution (second from the left).

Images rendered by realtime mode aren't saved to disk.

You can use the animation feature and a #switch(frame_number) structure or to 
use the clock variable to make the camera travel, to generate a serie of 
distinct images.
Another, manual, solution is to go and rename the just rendered image before 
rendering with the different camera.

The manual way is good for a few images.
The #switch is goos for retively few images where the various cameras are all 
distinct.
The use of clock is good if you want many positions along a path. The use if #if 
or #switch can be added if you want more than one trajectory.

Remember that, by default, clock goes from 0 to 1.
