Want to keep your content on your site only? Use one of the following right click blockers. Of course there are ways around it but many people will not know but it at least is a slight form of protection.

ALL CODE SHOULD BE PLACED IN <HEAD> </HEAD>

Script #1
Example:
http://members.shaw.ca/bavraj/norightclick/1.htm
This script will disable all right click of all kinds.
Code:
<!--

var message="No right click - Webmasterlingo.com";

function clickIE4(){
if (event.button==2){
alert(message);
return false;
}
}

function clickNS4(e){
if (document.layers||document.getElementById&&!document.all){
if (e.which==2||e.which==3){
alert(message);
return false;
}
}
}

if (document.layers){
document.captureEvents(Event.MOUSEDOWN);
document.onmousedown=clickNS4;
}
else if (document.all&&!document.getElementById){
document.onmousedown=clickIE4;
}

document.oncontextmenu=new Function("alert(message);return false")

// --> 
</script>

Script #2
Example:
http://members.shaw.ca/bavraj/norightclick/2.htm
This one will disable right clicking but I think is more subtle because it doesn't pop anything up.
Code:
<script language=JavaScript>
<!--



var message="";
function clickIE() {if (document.all) {(message);return false;}}
function clickNS(e) {if 
(document.layers||(document.getElementById&&!document.all)) {
if (e.which==2||e.which==3) {(message);return false;}}}
if (document.layers) 
{document.captureEvents(Event.MOUSEDOWN);document.onmousedown=clickNS;}
else{document.onmouseup=clickNS;document.oncontextmenu=clickIE;}

document.oncontextmenu=new Function("return false")
// --> 
</script>

Script #3
Example:
http://members.shaw.ca/bavraj/norightclick/3.htm
This script will only disable right clicking on the images which is a nice feature
Code:
<script language="JavaScript1.2">

var clickmessage="Images are not to be copied"

function disableclick(e) {
if (document.all) {
if (event.button==2||event.button==3) {
if (event.srcElement.tagName=="IMG"){
alert(clickmessage);
return false;
}
}
}
else if (document.layers) {
if (e.which == 3) {
alert(clickmessage);
return false;
}
}
else if (document.getElementById){

if (e.which==3&&e.target.tagName=="IMG"){
alert(clickmessage)
return false
}
}
}

function associateimages(){
for(i=0;i<document.images.length;i++)
document.images[i].onmousedown=disableclick;
}

if (document.all)
document.onmousedown=disableclick
else if (document.getElementById)
document.onmouseup=disableclick
else if (document.layers)
associateimages()
</script>
