hi,

yes you can display any picture you want in VC++ application window,
it basically depends on what format your picture file is in is it a bmp or a gif ?,
however the basic idea is to load the picture in a device context (CDC) and then bitblt it into the application window's OnPaint method.
please refer to MSDN the api calls such as CDC::BitBlt etc....
let me know if you need a sample program.

void CPaintDlg::ShowBitmap(CPaintDC *pdc, CWnd *pWnd)
{
// Convert the pointer to a pointer to the main dialog class
CGraphicsDlg *lpWnd = (CGraphicsDlg*)pWnd;
BITMAP bm;
// Get the loaded bitmap
lpWnd->m_bmpBitmap.GetBitmap(&bm);
CDC dcMem;
// Create a device context to load the bitmap into
dcMem.CreateCompatibleDC(pdc);
// Select the bitmap into the compatible device context
CBitmap* pOldBitmap = (CBitmap*)dcMem.SelectObject
CRect lRect;
// Get the display area available
GetClientRect(lRect);
lRect.NormalizeRect();
// Copy and resize the bitmap to the dialog window
pdc->StretchBlt(10, 10, (lRect.Width() - 20),
(lRect.Height() - 20), &dcMem, 0, 0,
bm.bmWidth, bm.bmHeight, SRCCOPY);
}
