FooGallery get wp_query to work

Hi, I using FooGallery and it’s great plugin for my gallery, but I want to include a 10 last elements in gallery to homepage in slider, so I don’t wan’t to use foogallery shortcodes, because they don’t support things, which I want to use, so I only want to get last 10 images src, only this, but I don’t know how to reach that.

So for example I have this:

$query = new WP_Query( array( 'post_type' => 'foogallery', 'p' => 123, 'posts_per_page' => 10 ) ); 
if ( $query->have_posts() ) : 
while ( $query->have_posts() ) : $query->the_post(); 
// Which code should I use to reach single image src? 
endwhile; 
endif;
