how are putting you image in MainFrame Window, i.e. View Window. have you overidden the OnDraw function for drawing image on View Window. you can use this class for display variety of image format on windows http://www.codeproject.com/bitmap/extendedbitmap2.asp[^]

I have an MDI app - and I wanted a less boring backdrop. The trick is to subclass the MDI Frame window - and then override WM_ERASEBKGND. The below code uses CSubclassWnd by Paul DiLascia - you should be able to search for in from an old MSJ article on the web. Good luck, Iain.

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CMDIFrameWnd::OnCreate(lpCreateStruct) == -1)
return -1;
m_Backdrop.Install (m_hWndMDIClient, IDB_MIDAS, 32);
....
return 0;
}

class CUIMDIBackdrop : public CSubclassWnd
{
public:
CUIMDIBackdrop ();
~CUIMDIBackdrop ();
BOOL Install (HWND hWndMDIClient, UINT idBitmap, int nMargin);

protected:
virtual LRESULT WindowProc(UINT msg, WPARAM wp, LPARAM lp);
};

CUIMDIBackdrop::CUIMDIBackdrop ()
{
}

CUIMDIBackdrop::~CUIMDIBackdrop ()
{
}

BOOL CUIMDIBackdrop::Install (HWND hWndMDIClient, UINT idBitmap, int nMargin)
{
// load resources and other graphics stuff here
return HookWindow (hWndMDIClient);
}

LRESULT CUIMDIBackdrop::WindowProc(UINT msg, WPARAM wp, LPARAM lp)
{
if (msg != WM_ERASEBKGND)
return CSubclassWnd::WindowProc(msg, wp, lp);

HDC hDC = (HDC) wp;
CDC \*pDC = CDC::FromHandle (hDC);

CRect rc;
::GetClientRect (m\_hWnd, &rc);

// do pretty stuff here
return TRUE;

}
