Digimarc isn't cheap. It creates a hidden watermark, by making very slight changes to an image according to a mathematical formula. Supposedly this will survive a lot of editing, and the theory is if you don't know it's there, you won't know to remove it. Like Nixon says, this is really meant to get you a victory in court after the fact, not to provide web security and make it impossible to grab the image.
I use the text mask tool. Right click the big
T in the tool palette, and choose "Horizontal Type Mask Tool," the one with marching ants and an arrow pointing right. Then click somewhere, type your mark, select another tool ( because while you're typing, shortcut keys don't work ), and you'll have a selection that looks like the letters. Finally, copy this to a new layer, and apply some effects to it, whether you want a gradient, flood fill, drop shadow, or anything else. I like this method because you can see detail in the image behind the text, and between the letters; this makes it a lot harder to clone the text away.
You can get the copyright symbol (
© ) on a PC by holding down the ALT key and typing 0169 on the numeric keypad.
I hope it's not inappropriate, or hijacking your thread, but since we're talking about creating visual effects in Photoshop, here's an example of what the technique I just spelled out produces:
The word "Forrest" would be fairly easy to clone out, because it's sitting on out of focus background with no detail. But the ©, and the Cr in my last name would be a little bit harder.
Finally, you can use html to lay a transparent gif or png image on top of the file you want to protect. This is far from full proof, but make it a little bit harder to grab your image, since right clicking and doing "save as" will only get you the empty file. Example:

Hope this helps a little.
