Not sure about a "hidden" watermark, but you can certainly draw a watermark onto an image control using the "d" functions in windev. Check out dStartDrawing and also the dCopyBlt() function. You will adjust the transparency to get the effect you want.
Cheers!

PS. In WebDev this can only be done at the server level.

To add to Ken's answer, here is a thread about hidden watermark done in Gimp:
http://www.gimpdome.com/index.php?topic=5971
If I understood correctly, Ken's method with a 2% opacity is about what the guy is doing to create the watermark in Gimp...
Seems to me that one of his method to REVEAL the watermark later on should work too...

i had a closer look, and if yo want to have a "solid" hidden watermark, you may want to consider an existing solution like

they even have a command line version for web servers, by example, and the windows GUI version contains a batch processing option too
