Hi Crush85,
I think By default it is getting setting from setting > reading > Blog pages show at most = 10
i have found the other solution if you can do changes in code ,here it is
Add a new argument
‘numberposts’ => -1
in rbxgallery.php line no. 148 in the function Bx_gal like this :
$args = array(
‘post_type’ => ‘attachment’,
‘post_mime_type’ => ‘image’,
‘numberposts’ => null,
‘post_status’ => null,
‘orderby’ => ‘menu_order’,
‘order’ => ‘ASC’,
‘post_parent’ => $post->ID,
‘numberposts’ => -1,
);
