Some of the pictures I downloaded to Lego Star Wars were "coprighted" so they had to be removed. I am really mad because there were no @%##*&? copyrights. If you want to see them, go to "Star Wars" at the link below. You will see the alternate models on the last few pages of the instruction booklet.
