trouble within g2 integrated in drupal: xampp

I've successfully integrated g2 into drupal 6.x

however any time I click through any album or photo shown inside drupal home page I get error - the system redirect myself through the XAMPP page (I have my drupal installed locally) . it looks like permission are not set out correctly. sync has been run successfully betw g2 and drupal.

is there any other things I might look at to fix this out?

thanks
