can you please tell me that how to add watermark to uploaded doc (pdf or image files).

The workflow will be-

User register at portal -> user upload some required document (like financial proof or some kind) -> When saving them to database -> a watermark (predefined by admin at backend in admin panel as - Logo or Text) will be added to those uploaded document on top and bottom or wherever possible on the uploaded document.

So in future when admin views the document uploaded by him in his account, it will be displayed with stamp or the whatermark. it will proof that the document is uploaded to server by user or whatever.  :P

Now, this we have found way to do in jpg, but in case of pdf its quite tough.. please guide.

Thanks..:)
