pas encore eu le temps... p-e ce matin pour une nouvelle image

Pour le srcipt pour une carte, ça ressemble à ça (il faudra l'adapter pour ta base de donnée et pour ton image):

dsl si c'est indigeste, j'ai pas retravillé bcp le code, j'ai juste ajouté qq commentaires.

Code :

<?php
include('../../includes/auth.inc.php');
$iMicroTime=microtime_float();
