I don't know of any way, offhand, so I threw together a little shell
script that appears to work (in UNIX at least).  Clip below (not
including) the line, call it "center" and make it executable.

And I wouldn't recommend centering pictures, unless they have two
straight margins (like a converted GIF).

while read line; do
  w1=`echo "$line" | wc -c`
  w2=`expr $half - $w1 / 2`
  if [ $w2 -gt 0 ]; then
    blank=`echo "$spaces"|cut -c-$w2`;
    echo "$blank""$line"
  else
    echo $line;
  fi;
done;
