Well for the thumbnail i use this code, it dosent open the whole
document, just extracts the embedded thumbnail picture.

BitmapEx TemplateAbstractView::scaleImg (const BitmapEx &rImg, long
width, long height)
{
    BitmapEx aImg = rImg;

    int sWidth = std::min(aImg.GetSizePixel().getWidth(),width);
    int sHeight = std::min(aImg.GetSizePixel().getHeight(),height);

    aImg.Scale(Size(sWidth,sHeight),BMP_SCALE_INTERPOLATE);

    return aImg;
}

BitmapEx TemplateAbstractView::fetchThumbnail (const rtl::OUString
&msURL, long width, long height)
{
    using namespace ::com::sun::star;
    using namespace ::com::sun::star::uno;

    // Load the thumbnail from a template document.
    uno::Reference<io::XInputStream> xIStream;

    uno::Reference< lang::XMultiServiceFactory > xServiceManager
(comphelper::getProcessServiceFactory());

    if (xServiceManager.is())
    {
        try
        {
            uno::Reference<lang::XSingleServiceFactory> xStorageFactory(
                xServiceManager->createInstance(
"com.sun.star.embed.StorageFactory"),
                uno::UNO_QUERY);

            if (xStorageFactory.is())
            {
                uno::Sequence<uno::Any> aArgs (2);
                aArgs[0] <<= msURL;
                aArgs[1] <<= embed::ElementModes::READ;
                uno::Reference<embed::XStorage> xDocStorage (
                    xStorageFactory->createInstanceWithArguments(aArgs),
                    uno::UNO_QUERY);

                try
                {
