Carrie, I think this is going to be a challenge no matter how you slice it but maybe this thread from StackOverflow might help.
For the images that get downloaded:
Now, for your documents that are on the system, I would suggest makign them all PDF and then use ITextSharp to watermark them on the fly. What you'll do in this case is with iTextSharp, open the PDF File on the server in memory, toss a watermark image onto
the pdf, then save it in the memory stream before rendering it to the client.
