在MFC中，您可以使用CImage类来实现图像控件。下面是一个示例，其中您可以使用“播放”按钮来连续播放规定数量的照片。

#include "afxwin.h"
#include "stdafx.h"
#include "MyPictureApp.h"
#include "MyPictureDlg.h"
#include "atlimage.h"

#ifdef _DEBUG
#define new DEBUG_NEW
#endif

CMyPictureDlg::CMyPictureDlg(CWnd* pParent /*=NULL*/)
    : CDialogEx(CMyPictureDlg::IDD, pParent)
{
    m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);
}

void CMyPictureDlg::DoDataExchange(CDataExchange* pDX)
{
    CDialogEx::DoDataExchange(pDX);
    DDX_Control(pDX, IDC_PICTURE, m_pictureCtrl);
}

BEGIN_MESSAGE_MAP(CMyPictureDlg, CDialogEx)
    ON_WM_PAINT()
    ON_WM_QUERYDRAGICON()
    ON_BN_CLICKED(IDC_BUTTON1, &CMyPictureDlg::OnBnClickedButton1)
END_MESSAGE_MAP()

BOOL CMyPictureDlg::OnInitDialog()
{
    CDialogEx::OnInitDialog();

    SetIcon(m_hIcon, TRUE);
    SetIcon(m_hIcon, FALSE);

    return TRUE;
}

void CMyPictureDlg::OnPaint()
{
    if (IsIconic()) {
        CPaintDC dc(this);

        SendMessage(WM_ICONERASEBKGND, reinterpret_cast<WPARAM>(dc.GetSafeHdc()), 0);

        int cxIcon = GetSystemMetrics(SM_CXICON);
        int cyIcon = GetSystemMetrics(SM_CYICON);
        CRect rect;
        GetClientRect(&rect);
        int x = (rect.Width() - cxIcon + 1) / 2;
        int y = (rect.Height() - cyIcon + 1) / 2;

        dc.DrawIcon(x, y, m_hIcon);
    } else {
        CDialogEx::OnPaint();
    }
}

HCURSOR CMyPictureDlg::OnQueryDragIcon()
{
    return static_cast<HCURSOR>(m_hIcon);
}

void CMyPictureDlg::OnBnClickedButton1()
{
    CImage image;
    int num_images = 2;
    for (int i = 0; i < num_images; i++) {
        CString
