I have a client who does not want people to copy images from his site. How can I protect them?

Um, by not showing them? I've heard of people catching the right mouse click using javascript to prevent the "save image as" menu from being shown, but even with that precaution the browser has probably already saved the image to the cache on the user's computer. They could read the source of the HTML and download the file directly. If someone is half-knowledgable about the Windows platform, they know that pressing the "Shift" and "Print Screen" buttons copies the content of the screen to the clipboard, and one can paste that content into any image editor. If someone wants an image that is placed on the internet, they will get it. Their best bet is to place an obvious copyright on the image and send "Cease and Desist" notifications to anyone who tries to use them.

Or I could hit alt-print screen and copy the image to my word processor or graphics program. Or I could take out my digital camera and take a picture of the screen.
How about this request... I want to display text on the screen but not allow anyone to copy it.

Catching the right click with JavaScript will stop many users, so that's good for something, you might as well do it. But it certainly can't be regarded as an absolute protection. In addition to what others have already listed, the user could simply disable JavaScript. As Joe suggests, an embedded copyright is probably best.

OK, next question, I am a total Java greenhorn. Had one semester of java programing and barely lived to tell about it. Im an artist not a programer. How would I code that?

Never mind on that code. Told the client what you all said and he told me to not waste my time on it. Thank goodness.
Thanks for the input
