bonjour si tu veut mettre un id c'est a cette endroit en faisant l’incrémentation d'une variable cree en amon


picReader.addEventListener("load",function(event){

var picFile = event.target;

var div = document.createElement("div");

div.id=id+variable_a_incrementer
variable_a_incrementer++

div.innerHTML = "";

output.insertBefore(div,null);
