Unfortunately there is no legal way to control it. But there is a dirty way to do it… If you select this route, then you will need to : clone the standard gallery_shortcode function add a default value for $attr[‘link’] option hook your cloned function into post_gallery filter The final result will look like this: … Read more
It looks like the nightly builds of the Advanced Custom Fields plugin can (mostly) handle this now, so you could try installing that. Details on this support issue. I can’t update my copy of it to test right now but this is what it would look like in the admin:
You can try the following to clear the image attachment’s title when it’s inserted but not updated: /** * Empty the image attachment’s title only when inserted not updated */ add_filter( ‘wp_insert_attachment_data’, function( $data, $postarr ) { if( empty( $postarr[‘ID’] ) && isset( $postarr[‘post_mime_type’] ) && wp_match_mime_types( ‘image’, $postarr[‘post_mime_type’] ) ) $data[‘post_title’] = ”; return … Read more

I think this is possible but appears to be a bit more involved. Certain classes and markup are required in the output for … Read more
