You are probably trying to do something really ugly that would better be 
  done in a different way.  The clock variable can't be set from within 
the POV-SDL file so there is no reason to set the output file name 
depending on it from there either.  Both can only be specified as 
command line/ini file options.

There are dozens of possible ways to accomplish this, the most simple 
probably is (as shell script, should be possible as Windows batch file 
as well):

for TEXTURE in *.jpeg ; do
   echo "#declare TEXTURE_FILE=\"$TEXTURE\"" > image_file.inc
   povray -iscene.pov -o${TEXTURE}_pov.png
done

Where scene.pov of course #includes image_file.inc and uses TEXTURE_FILE 
then.

Using the internal animation loop of POV-Ray would be possible as well 
but somewhat more complicated (generating an array of image file names 
would be possible as well as writing a file list to be read via #read).
