[Scripting Question] Essentials 1.18.1 - Show picture with a script.

[ZonaZeroDgameplay]

Hi all of you!

You will see. I am trying to modify the following script so that while the game is accelerated, an image is displayed on the screen, above the game layer itself but below the menus. Just like in Pokémon Insurgence!

# SPEEDUP_STAGES are the speed stages the game will pick from. If you click F, #
# it'll choose the next number in that array. It goes back to the first number #
#                                 afterward.                                   #

#             $GameSpeed is the current index in the speed up array.           #
#   Should you want to change that manually, you can do, say, $GameSpeed = 0   #
#                                                                              #
# If you don't want the user to be able to speed up at certain points, you can #
#                use "pbDisallowSpeedup" and "pbAllowSpeedup".                 #

def pbAllowSpeedup
  $CanToggle = true
end

  $CanToggle = false

# Default game speed.
$GameSpeed = 0
$frame = 0
$CanToggle = true

module Graphics
  class << Graphics
    alias fast_forward_update update
  end
  
  def self.update
    if $CanToggle && Input.trigger?(Input::ALT)
      $GameSpeed += 1
      $GameSpeed = 0 if $GameSpeed >= SPEEDUP_STAGES.size
    end
    $frame += 1
    return unless $frame % SPEEDUP_STAGES[$GameSpeed] == 0
    fast_forward_update
    $frame = 0
  end
end

module Input
  class << Input
    alias fast_forward_button_to_key buttonToKey
  end
  
  F = 50
  
  def self.buttonToKey(btn)
    return [0x46] if btn == Input::F
    fast_forward_button_to_key(btn)
  end
end

Is it possible?
