I used the code by macgamer

// return photon server to use based on url 

function static_counter( $url ) {
        srand( crc32( basename( $url ) ) );
        $static_counter = rand( 0, 2 );
        srand(); // this resets everything that relies on this, like array_rand() and shuffle()

        return $static_counter;
}

// fetch photon equivalent url

function photon_url($url) {

	if (strpos($url,'http://') !== false)
	{
	   $url=str_replace('http://','',$url);
	}

	return "http://i".static_counter($url).".wp.com/".$url;
}

and I replaced the_post_thumbnail(); with

$featured_image = wp_get_attachment_image_src(get_post_thumbnail_id($post->ID)); // get thumbnail image url

$photon_featured_image = photon_url($featured_image[0]);

echo "<img src='".$photon_featured_image."' class='wp-post-image'> ";
