php - Gmail tracking image not tracking -


i put own track image track opens (when user clicks on email open it).

image: https://segmentation.eu/gmailer/david/soy-una-imagen.php

the php of image is:

<?php header("content-type: image/jpeg"); // porque soy una imagen  readfile("pipi.jpg");  //llamar los datos de configuración include('../super-config.php');  //conectar mysql $bdnik=new mysqli($host_db, $usuario_db, $clave_usuario_db, $nombre_db); $bdnik->set_charset("utf8");  //¿estamos conectados? if($bdnik->connect_errno){ printf("no fue posible conectar la base de datos: %s\n", $bdnik->connect_error); exit(); }  //blablabla log , stufff   $bdnik->query("insert gm_trackeame (planb) values (1)"); ?>

but problem is not tracking... google removes image when sent programattically via app.... strange.

also, when send via gmail web, gets new url.
