Я проверил ваш SSCCE - спасибо, что опубликовал его, и одна проблема, которую я обнаружил, была с ошибкой цикла for. Попробуйте изменить это:
for (int x = 0; x > imageList.size(); x++) {
imageArray[x] = new ImageIcon(imageList.get(x));
//....
}
к этому:
for (int x = 0; x < imageList.size(); x++) {
imageArray[x] = new ImageIcon(imageList.get(x));
//....
}
Я не уверен, является ли это ошибкой в вашей реальной программе или это просто ошибка в SSCCE, но она критична.
