    Best regards, I want to change the name of the automatic image with the title of the post.

    For example, I have the image called 1231231252345.jpg and Title of the article is "Article for a test", I want to change the name of the image in "article-for-a-test.jpg"

    I think what you're looking for is the filter: wp_handle_upload_prefilter.

    From the Codex:

    The single parameter, $file, represent a single element of the $_FILES array. The wp_handle_upload_prefilter provides you with an opportunity to examine or alter the filename before the file is moved to its final location.

    Example code from the Codex:

    add_filter('wp_handle_upload_prefilter', 'custom_upload_filter' );

function custom_upload_filter( $file ){
    $file['name'] = 'wordpress-is-awesome-' . $file['name'];
    return $file;
}

    How to use this hook

    add_filter( 'wp_handle_upload_prefilter', 'custom_upload_filter' );
function custom_upload_filter( $file ) {
    if ( ! isset( $_REQUEST['post_id'] ) ) {
        return $file;
    }
    $id           = intval( $_REQUEST['post_id'] );
    $parent_post  = get_post( $id );
    $post_name    = sanitize_title( $parent_post->post_title );
    $file['name'] = $post_name . '-' . $file['name'];
    return $file;
}

    Found this article but unable to put it on place: https://wordpress/support/topic/how-to-auto-rename-based-on-current-post-title-a-media-defined-as-featured-image/
