It is really called TkPhotoImage; and you have to call new()
   image = TkPhotoImage.new("file" => "some.gif")

What about TkButton.new(root)  # what bottom? pack('side' => 'bottom')
In general, do not forget the semicolons in between ``options'' of this block.

What lacks in your example is
  require 'tk'
in the beginning and
  Tk.mainloop
at the end. But I think you already knew that...
