    if not (os.path.isfile(path_to_ppt) and os.path.isdir(path_to_folder)): 
        raise "Please give valid paths!" 
  
    powerpoint = comtypes.client.CreateObject("Powerpoint.Application") 
  
    # Needed for script to work, though I don't see any reason why... 
    powerpoint.Visible = True 
  
    powerpoint.Open(path_to_ppt) 
  
    # Or some other image types 
    powerpoint.ActivePresentation.Export(path_to_folder, "JPG")

    powerpoint.Presentations[1].Close() 
    powerpoint.Quit()
