about require 'photo'

hi, I am new to fxruby. I am trying out example given in FXRuby_Create_Lean_and_Mean_GUIs_with_Ruby_-Pragmatic_Bookshelf . I am stuck at require ‘photo’ line in picturebook.rb this is giving me error as no such file to load. I tried gem install photo , but it says no gem repository. Can you help me..

It’s not a gem, it’s part of the PictureBook example that’s laid out in the book. Do copies of the book that you download from file sharing sites not include Chapters 3-6?

thank you, I got it.

Hello, guys.
I have win xp.
There is photo.rb in the folder with picturebook.rb
But still my ruby tells me about mistake:

 <internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- photo (LoadError)
        from <internal:lib/rubygems/custom_require>:29:in `require'                              
        from picturebook.rb:15:in `<main>'     

Already find an answer by myself.
Because I use Ruby 1.9.2 – it no longer makes the current directory . part of my LOAD_PATH
so better do

reqiure '.\photo.rb'
