Pager does not seem to work in View

I created a view to act as gallery navigation for a group of 45 images on my site. The first page works correct as it displays 9 thumbnails and items per page is set to 9. Use pager is selected and 'full pager' has been chosen. If I set the number of items per page to 9, 18, 36, or 45, all images display correctly on the first page; however, no matter what, a second (third, fourth, or fith) page is not displayed.

You can see the view at http://www.futuresite.villacollectionsdesign.com/gallery and I am putting in the view's export code below:

$view = new view;
$view->name = 'Gallery';
$view->description = '';
$view->tag = '';
$view->view_php = '';
$view->base_table = 'node';

$view->api_version = 2;
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */
$handler = $view->new_display('default', 'Defaults', 'default');
