* Introduced two new attributes of MainWindow: cur_img_idx - Index of current image in m_img_list. img_count - Length of m_img_list. * Implement counter_str method to get string representation of counter. * Appended counter to window title. * Based image switching logic on counter instead of local variables. * Removed useless condition. current_index = self.m_img_list.index(ustr(item.text())) if current_index < len(self.m_img_list): list.index will raise ValueError if item doesn't exist.
