I tried your demo link in FF and the Classic Green is showing up not even your demo template. I tried it several times.
Switch the template using the template switch sidebox, or go to this url:

http://www.picaflor-azul.com/free-de...erdeen_neutral


and navigate to product number 25 "Microsoft Internet Keyboard PS/2".


I looked at your site and your code is not working because you have edited the tpl_product_info.php file and have problems with your code. Just from a quick glance I see that you have tried to move the additional images.
