Im not sure how do this?… which file do I add the code to?…..
If you want to customize the look of the Tiled Galleries, it would probably be better to completely remove Jetpack’s Tiled Gallery libraries, like so:
function tweakjp_rm_tiledlibs(){
wp_dequeue_script( ’tiled-gallery’ );
wp_dequeue_style( ’tiled-gallery’ );
}
add_action( ‘wp_footer’, ‘tweakjp_rm_tiledlibs’ );
