I think this is saying that Microsoft defined their own codec for image storage in MS Office 2003. On one google result that I found, it appears that MS has abandoned this image format in later versions of MS Office. Is this what you were saying? Also, isn't OLE (Object Linking and Embedding) another MS-only standard that doesn't help anyone using a non-MS platform? Thanks, Gene Amtower
