Use the script below so when someone right clicks to save an image off your page, a message will come up letting people know that your information is copyrighted.
This script may not work in all browsers, and is not foolproof. If someone really wants something from your page they can find ways around it, but at least it's a warning to people who want to take your graphics. But it certainly is a great start.
Copy and paste the following code, and make sure it comes right after your <HEAD> tag:
<script language=JavaScript> var message="Function Disabled!"; 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>
