Hi guys..I am trying to display a series of image in qlabel..i dono where i am going wrong. when i click the qpushbutton it displays only the last image rather displaying from beginning. Below is my code

mainwindow.cpp

#include "mainwindow.h"
QLabel *FirstLabel = NULL;
QLabel *SecondLabel = NULL;
QLabel *ThirdLabel = NULL;
MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
{
 
    FirstLabel = new QLabel(this);
    FirstLabel->move(0,240);
    FirstLabel->resize(this->x()+400,this->y()+240);
    FirstLabel->show();
 
    QPushButton *train_button = new QPushButton(this);
    train_button->setText(tr("something"));
    train_button->move(200,200);
    train_button->show();
 
    connect(train_button, SIGNAL(clicked()),
            this, SLOT (PlayImage()));
}
 
void MainWindow::PlayImage()
{
    char* picture[5] =  {"D://1.png","D://2.jpg","D://3.jpg","D://4.jpg","D://5.jpg"};
    for(int i = 0;i<=4 ; i++){
    QPixmap pixmapObject(picture[i]);
    FirstLabel->setPixmap(pixmapObject);
    update();
    }
}
 
MainWindow::~MainWindow()
{
}

#include "mainwindow.h"
QLabel *FirstLabel = NULL;
QLabel *SecondLabel = NULL;
QLabel *ThirdLabel = NULL;
MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
{

    FirstLabel = new QLabel(this);
    FirstLabel->move(0,240);
    FirstLabel->resize(this->x()+400,this->y()+240);
    FirstLabel->show();

    QPushButton *train_button = new QPushButton(this);
    train_button->setText(tr("something"));
    train_button->move(200,200);
    train_button->show();

    connect(train_button, SIGNAL(clicked()),
            this, SLOT (PlayImage()));
}

void MainWindow::PlayImage()
{
    char* picture[5] =  {"D://1.png","D://2.jpg","D://3.jpg","D://4.jpg","D://5.jpg"};
    for(int i = 0;i<=4 ; i++){
