Removing WordPress Default Image Link

When uploading images to your WordPress media library, different copies of the images in different sizes are created. It also adds a link to the image by default. If you want to remove this default link for good simply edit your functions.php file by adding this code
function wpb_imagelink_setup() {
$image_set = get_option( 'image_default_link_type' );

if ($image_set !== 'none') {
update_option('image_default_link_type', 'none');
}
}
add_action('admin_init', 'wpb_imagelink_setup', 10);

Nice, but If any want to Remove some pictures then its not good for those peoples. It's best for those people how want remove link all picture other people follow this way

• Add your Picture in post or page
• Then click on the picture and GOTO to pictures setting
• Remove link URL or change it what you want

Thank for the tip.
