@daviddddd,
You could create the gallery and change the path to make this your store page.
If you want display the most recent gallery, you can create a page template and use the following code:
$gallery = wp_query(array('post_type'=>'ims_gallery', 'posts_per_page'=>1));
if ( $gallery->have_posts() ) {
while ( $gallery->have_posts() ) { $gallery->the_post();
the_content( );
}
}
