def self.__define_LoadImages_proc_for_compatibility__!
  # Ttk 8.5 (Tile 0.8) lost 'LoadImages' utility procedure.
  # So, some old scripts doen't work, because those scripts use the 
  # procedure to define local styles. 
  # Of course, rewriting such Tcl/Tk scripts isn't difficult for 
  # Tcl/Tk users. However, it may be troublesome for Ruby/Tk users 
  # who use such Tcl/Tk scripts as it is.
  # This method may help Ruby/Tk users who don't want to modify old 
  # Tcl/Tk scripts for the latest version of Ttk (Tile) extension.
  # This method defines a comaptible 'LoadImages' procedure on the 
  # Tcl/Tk interpreter working under Ruby/Tk. 
  # Please give attention to use this method. It may conflict with 
  # some definitions on Tcl/Tk scripts.
