Jlist Image et Panel

salut,
je n'arrive pas á utiliser Jlist. En fait j'ai une classe qui me permet de prendre des photos à partir d'une webcam. Les images sont affichées dans un Frame composé de trois panel: un panel pour la webcam un autre pour un bouton qui me permet de capturer l'image et enfin un autre pour afficher l'image capturée. En ce qui concerne le panel pour l'image capturer j'ai une classe ImagePanel qui fait ce travail:

Mon problem est le suivant: lorsque je prends la première photo elle s'affiche dans le panel correspondant et ensuite si je prends la deuxième elle prend la place de la première. Pour que toutes les photos prisent soient visualiser par l'utilisateur j'ai pensé a un Jlist d'image et alors j'ai essayé ceci:

				int height = (int)(myImg.getHeight(null)*0.3);

en fait j'ai remplacé la classe setImage de ImagePanel dans SwingCapture par jlist(). ca ne fonctionne pas.
Quelqu'un pourait il m'aider svp?
Merci d'avance.
