I'll see what I can scavenge from the excellent Foxypreviewer as well, since it has had report watermarking for years.

One thing did occur to me: using vector images yields better quality in a report, but it's probably quite easy to erase a watermark from a vectorized image compared to a png or bmp that weaves it into the other pixels. Might have to change back to images!
