Maybe you should visit
www.scripts.com
or search on google with "right click disabled" + javascript or something like that.
There are various combination scripts that you can try out, if you do not want anyone to copy your code and images then along with the no-right clikc code you have got to mae sure that in the Internet browser toolbar in the 'view' menu, the 'source' option is disable or not present.
Also you can get a script that allows you to right-click on the page and even see the code, but when you try to save a image and try to right-click on it, it does not allow you to.
Still people are going to find way to copy your stuff, but atleast you can make it harder for them :)
