A digital watermark is a "digital signature" in the bits that make up a computer graphic that identify the author or owner of the image. Ideally the watermark doesn't cause the image to look any diferent, but it can be identified by using a specialpiece of software to search for the watermark in a given image. You might use this if you were a photographer with a website. If you watermarked your images, you could actually prove that someone stole one and used it on his own site without permission.
This is completely different from attempting to disable the right-click menu. There are a myriad of problems with attempting to do this, starting with the simple fact that not all web surfers have a mouse with two buttons! If you get to the root of WHY someone wants to disable the right-click, it's usually to hide source or disable downloading of images. Guess what...you don't need the right click to get those things. Visit a newsgroup like comp.infosystems.www.authoring.html or comp.lang.javascript to get the long story on this.
