Image post format not showing up

Hello,

Try to add the below code to the child theme’s functions.php file and check it works or not –

function owp_pf_support() {
    add_theme_support( 'post-formats', array( 'aside', 'gallery', 'link ', 'image', 'quote', 'status', 'video', 'audio', 'chat' ) );
}
add_action( 'after_setup_theme', 'owp_pf_support' );
