link to page on thumbnails

Hi there. I have the following shortcode in my footer widget on my site but need each thumbnail pic to link to an internal page. Any idea on that?

[ngg_images gallery_ids=”1″ display_type=”photocrati-nextgen_basic_thumbnails” override_thumbnail_settings=”1″ show_slideshow_link=”0″ number_of_columns=”3″ thumbnail_width=”65″ thumbnail_height=”auto”]
