Bonjour,
Je suis entrain de faire une application qui pose des questions et qui a tribu un score a la fin.
Je suis bloqué sur un point :
Je cherche à mettre une image pour chaque questions mais sa ne fonctionne pas, quelqu’un peut-il m’aider ?
Volontairement je n’est pas mis tous le programme a fin que le message ne soit pas trop grand
Si dessous en rouge ce que j’ai fait pour mettre l’image qui ne fonctionne pas :
