Show picture

[mor]

Hi,
I want to use in my game that script:

#--------------------------------------------------------------------------
  # * Show Picture
  #--------------------------------------------------------------------------
  def command_231
    # Get picture number
    number = @parameters[0] + ($game_temp.in_battle ? 50 : 0)
    # If appointment method is [direct appointment]
    if @parameters[3] == 0
      x = @parameters[4]
      y = @parameters[5]
    # If appointment method is [appoint with variables]
    else
      x = $game_variables[@parameters[4]]
      y = $game_variables[@parameters[5]]
    end
    # Show picture
    $game_screen.pictures[number].show(@parameters[1], @parameters[2],
      x, y, @parameters[6], @parameters[7], @parameters[8], @parameters[9])
    # Continue
    return true
  end

I have many pictures and its easier for me to use script because I can use some indeks instant of number of pictures
But My problem its that I dont get this scirpt especially parameters.
Can someone help me?
