Office 2007 files thumbnails

Hi guys,

I would like to add thumbnails to Office 2007 uploaded files (xlsx, docx, pptx etc.) just like it does for office 2003 files (doc, xls, ppt etc)

I have noticed that there is an images/icons folder within ckfinder containing thumbnails (16, 32) for most of the common files including office 2003 but no office 2007.

Could anyone please let me know how to add thumbnails for Office 2007 files?

Regards,
Nabeel Farid
