Hi Anh Tran
Ok how to solve this validation for image upload is very important. Can you provide any quick solution thanks

i added setting same problem

function mb_allow_subscriber_uploads() {
    if ( is_admin() ) {
        return;
    }

    // Replace 'subscriber' with the required role to update, can also be contributor.
    $subscriber = get_role( 'subscriber' );
    $subscriber->add_cap( 'upload_files' );
    
    
    
}
add_action( 'init', 'mb_allow_subscriber_uploads' );

Hi please check the following code

array(
                'id'               => 'gallery_upload',
                'name'             => esc_html__( 'Image Upload', 'your-prefix' ),
                'type'             => 'image_upload',
                'admin_columns' => 'before title',
                'required'   => true,
                // Delete image from Media Library when remove it from post meta?
                // Note: it might affect other posts if you use same image for multiple posts
                'force_delete'     => true,
                // Maximum image uploads
                'max_file_uploads' => 5,
                // Display the "Uploaded 1/2 files" status
                'max_status'       => true,
            ),
