}
add_action( ‘wp_enqueue_scripts’, ‘img_gallery_blog_house’ );

function img_gallery_loop ($atts, $content = null){

extract ( shortcode_atts ( array (

), $atts, ‘img-gallery’) );

return ‘<div class=”main”>’ . do_shortcode($content) . ‘</div>’;
}
add_shortcode (‘img-gallery’, ‘img_gallery_loop’);

function gallery_imgs_loop ($atts){
