Bonjour, _AsX_;
je viens de faire des essais et cela fonctionne (PHP5 et MySQL5). Quand je rafraîchis la page hôte de l'image aléatoire, celle-ci change bien, en fluctuant d'une catégorie à l'autre. Bien sûr, de temps à autre, deux images de la même catégorie peuvent se succéder, mais c'est le principe même des séries aléatoires.
Voici le code exact que j'ai utilisé pour le fichier random.php lors de mes tests:
