Recherchez le fichier image et de l'afficher à l'aide de Java Swing

Mon problème, c'est,
après avoir cliqué sur Parcourir bouton, il affiche tous les fichiers dans un répertoire de choisir,
ensuite, l'image choisie est affichée dans l'interface utilisateur correctement. Mais Lorsque je clique sur le bouton Parcourir
pour la deuxième fois, il montre l'ancienne image seulement, au lieu de montrer la nouvelle. Merci de m'aider dans cette.

Pour la référence, j'ai téléchargé l'INTERFACE utilisateur.
