Here's quick and dirty example:

----------------
#include <windows.h>
#import <olepro32.dll>

int _tmain(int /*argc*/, _TCHAR* /*argv*/[])
{
    ::OleInitialize(NULL);

    _variant_t vtPath(L"C:\\Temp\\Cool.jpg");

    IDispatchPtr ptrDisp;

    HRESULT hr = ::OleLoadPictureFile(vtPath, &ptrDisp);

    if(SUCCEEDED(hr))
    {
        IPicturePtr ptrPicture(ptrDisp);

        OLE_HANDLE hBmp = NULL;
        ptrPicture->get_Handle(&hBmp);

        if(hBmp)
        {
            BITMAP bm = { 0 };
            int nRet = ::GetObject((HANDLE)hBmp,
                            sizeof(BITMAP), &bm);

            if(nRet)
            {
                // use BITMAP
            }
        }
    }

    ::OleUninitialize();

    return 0;
}
