export or insert an Image to MS WORD 2007

Question

Hi all,
How can export or insert an Image of type metafile to MS WORD 2007.
Doc.InlineShapes.AddPicture() needs an Image file stored on disk space, But I dont have Image file.What I have is an Image object.
When I tried to copy it from Clipboard, it didnt support the metafile.
So is there any other method to insert an Image to WORD.
Thank you.
