Aside from IPicture::Render, you can also display the picture using other functions. You can use BitBlt() for bitmaps, or PlayMetaFile() for metafiles. You can also extract the handle to the picture by calling IPicture::get_Handle(). You can cast the handle to the appropriate type; that is, for example HBITMAP, HICON, and HMETAFILE. To determine what type of handle to cast it to, call IPicture::get_Type().
