Subject: FXRuby problem

I'm trying to write a small FXRuby program that will
capture 6 pictures from a web source and place them as
buttons on my window. After that I want to have the
buttons to update with a new picture once every second
or so.
This is the work in progress I have a small
explanation below
=========== BEGIN CODE ==============

#!/usr/bin/env ruby

require "fox"
require "cam.rb"
include Fox
include Cam

class TestWindow < FXMainWindow
  def initialize(app)
    @app = app
    # Invoke the base class initialize first
    super(@app, "Test", nil, nil, DECOR_ALL, 0,
0,640,480)
    @picture_matrix = FXMatrix.new(self, 2,
LAYOUT_TOP|LAYOUT_FILL_ROW)

    @photo_array = []
    (1..6).each do |j|
      @photo_array[j] = FXButton.new(@picture_matrix,
"photo #{j}", create_photo_icon(j), app,
FXApp::ID_QUIT, ICON_UNDER_TEXT|JUSTIFY_BOTTOM)

      #@photo_array[j] = FXImage.new

    end
  end

  def create
    super
    show(PLACEMENT_SCREEN)

    @photo1Thread = Thread.new(@photo_array[1]) do
|photo1|
      while true

        photo1=FXButton.new(@picture_matrix, "photo
1", create_photo_icon(1), @app, FXApp::ID_QUIT,
ICON_UNDER_TEXT|JUSTIFY_BOTTOM)
        sleep(1)
      end
    end

  end

  def create_photo_icon(i)
    getImageData(i) #This saves a picture capture as
"photo#{i}.jpg" (it's in the cam module)
    p i
   
icon=FXJPGIcon.new(@app,File.open("photo#{i}.jpg","rb").read)
    icon.scale(120,150)
    return icon
  end
end


def run
  application = FXApp.new("DirList", "FoxTest")
  application.init(ARGV)
  TestWindow.new(application)
  application.create
  application.run
end

run

======END CODE==========

in the create method is a thred that is supped to be
updating button 1 every second, (It will hopefully be
expanded to all 6 buttons an a round-robin fasion) 
But the picture on the button is not updating and I
can't figure out why. I've tried everything like
repaints and refreses and it simply ignores the new
button information. Why? Can anyone help?

-Thanks
