Standard of wordpress Gallery

To update the default link type of images moving forward, you can do this by accessing your site options at yourdomain/wp-admin/options.php

Scroll down and find the image_default_link_type field. You have 4 choices:

1. none – This links back to the post it was uploaded to
2. file – This links to the image file in your wp-content/uploads folder
3. post – This links back to the post it was uploaded to
4. attachment – This links to an attachment post generated by WordPress for all image files uploaded to a post

You can also do this with a function in functions.php:

function mytheme_setup() {
 update_option('image_default_link_type', 'file' );

}
add_action('after_setup_theme', 'mytheme_setup');

Here’s a video I created that outlines how the Function above works and how to install on your WordPress site:

You don’t have to change the Function name. You can, as long as it’s the same in both places. Also, it does not matter where you add this function to your theme’s functions.php file. Sometimes you have to add a function before calling the filter, and a priority order, but it should not matter with this function.

On testing, however, I see that I was mistaken on this functionality working for image galleries, it does not.

To update the default image linking behavior for image galleries, please use this function:

add_filter( 'shortcode_atts_gallery',
    function( $out ){
        $out['link'] = 'file'; 
        return $out;
    }
);

Here is an updated video outlining the new Function, and how it works with the default linking behavior for galleries on a new install of WordPress:
