Can "add_attachment" be used to uploads thumbnails? (1 post)

    I'm using the "add_attachment" to sync images and video files to Amazon S3. But this doesn't seem to process any of the custom thumbnails. e.g. the original image will get sent to s3, but the 150x150 thumbnail won't get passed this same upload function. Any ideas would be greatly appreciated.

    add_action( 'add_attachment', function($attachment_ID) {
        $s3 = S3Client::factory();
        $s3_credentials = new Credentials('x', 'x');
        // get the path to the uplaoded file
        $attachment = get_attached_file($attachment_ID);
        // filename
        $key = basename($attachment);
        $mimes = array(
            'webm'  => 'video/webm',
            'mp4'   => 'video/mp4',
            'flv'   => 'video/x-flv',
            'ogv'   => 'video/ogg',
            'jpg'   => 'image/jpeg',
            'png'   => 'image/png'
        // check to see if it's an allowed file type
        $allowed_files = array('webm', 'mp4', 'flv', 'ogv', 'jpg', 'png');
        $filename = explode('.', $attachment);
        $file_ext = end($filename);
        if (in_array($file_ext, $allowed_files)) {
            $result = $s3->putObject(array(
                'ACL'           => 'public-read',
                'Bucket'        => 'bucket-name',
                'ContentType'   => $mimes[$file_ext],
                'Key'           => $key,
                'SourceFile'    => $attachment
