Cette application Gtk affiche un fichier image issu du dossier en cours.

  <note>
Si le fichier image n'est pas chargé correctement, l'image contient une icône en forme d'« image brisée ». Le <file>nomdufichier.png</file> doit être dans le dossier actuel pour que ce code fonctionne. Faites bon usage de votre photo favorite !
