BOOL GetUrlCacheEntryInfo(
  __in          LPCTSTR lpszUrlName,
  __out         LPINTERNET_CACHE_ENTRY_INFO lpCacheEntryInfo,
  __in_out      LPDWORD lpcbCacheEntryInfo
);

DWORD dwEntrySize = 0;
LPINTERNET_CACHE_ENTRY_INFO lpCacheEntry;
if (!GetUrlCacheEntryInfo( IMG_PATH, NULL, &dwEntrySize))
{
    if (GetLastError()!=ERROR_INSUFFICIENT_BUFFER)
        return;
    else
        lpCacheEntry = (LPINTERNET_CACHE_ENTRY_INFO)new BYTE[dwEntrySize];

    if (GetUrlCacheEntryInfo( IMG_PATH,lpCacheEntry, &dwEntrySize))
    {
        {
            ::CopyFile( lpCacheEntry->lpszLocalFileName
                , GetAppPath() + _T("out.jpg")
                , FALSE
                );
        }

    }
    delete lpCacheEntry;
}
