Vous pouvez aussi charger les photos individuellement via la fiche de chaque étudiant (menu "Etudiant" / "Changer la photo").
Cette page permet de charger en une seule fois les photos de plusieurs étudiants.
Il faut d'abord remplir une feuille excel donnant les noms
des fichiers images (une image par étudiant).
Ensuite, réunir vos images dans un fichier zip, puis télécharger simultanément le fichier excel et le fichier zip.
