Pop up MSG BOX, Prevents/annoy ppl who right click Options

[Sweet_Lemon_Tea]

I was wondering if there's a code that prevents/annoy ppls who right click to steal images and pics from my site.

I'm looking for a code that will pop up a personalized message box like "Watch it, back off!" or something like that each time a person tries to right click to steal something from my xanga site...

I got given several codes, but none of them work.......is it because I put the code into the wrong place? I put the code into the "OUR HTML" in the Look and Feel section..

Here are some of the codes that were given to me:

CODE 1)

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")

// -->

CODE 2)


var message="Copyright 2003 by INSERT YOUR NAME HERE. STOP TRYING TO STEAL MY CODE YA N00B!!!.";
function click(e) {
if (document.all) {
if (event.button==2||event.button==3) {
alert(message);
return false;
}
}
if (document.layers) {
if (e.which == 3) {
alert(message);
return false;
}
}
}
if (document.layers) {
document.captureEvents(Event.MOUSEDOWN);
}
document.onmousedown=click;
