Hi
Googled a bit and found some scripts for this function. There are many examples out there doing different thing when you rightclick. One of the better solutions I've seen is to initiate a pop-up with copyright info. Since the visitor can get the images whatever you do(There's always printscrn if all else fails), saying that the image belongs to you and asking the visitor to respect this is as far as you'll get. So, google around a bit using searchwords like "javascript +rightclick" and you'll find a solution that matches your needs. Here's some examples I found:
-------------------------------------------------
script 1
<head>
<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;}
// -->
</script>
</head>
-------------------------------------------
Script 2
<SCRIPT>
document.oncontextmenu=gris;
function gris () {
return false;
}
</SCRIPT>
-------------------------------------------
script 3
<SCRIPT language="javascript" type="text/javascript">
<!--
// please keep these lines on when you copy the source
// made by: Max - 2001 .";
var mymessage = "Sidan är kopieringsskyddad © Max.";
function rtclickcheck(keyp)
{if(navigator.appName == "Netscape" && keyp.which == 3)
{alert(mymessage);
return false;}
if (navigator.appVersion.indexOf("MSIE") ! = -1 && event.button == 2)
{ alert(mymessage);
return false;}}
document.onmousedown = rtclickcheck
//-->
</SCRIPT>
