A little off-topic, but suppressing right-clicks (and trying to suppress Ctrl/Alt/Shift?) is a really obnoxious thing for a website to do.
document.onmousedown=disableclick;
status="Sorry, not sharing images!";
function disableclick(event)
{
if(event.button==2)
{
alert(status);
return false;
}
}
function detectspecialkeys(e){
var evtobj=window.event? event : e
if (evtobj.altKey || evtobj.ctrlKey || evtobj.shiftKey)
alert("The key is not available.");
}
document.onkeypress=detectspecialkeys
