Today the articles, photos are copied by others is a common in web. The blogger can disable others in coping their articles and photos he own. The process is very simple. I came to know this method from simplex and for main source you may visit Dynamic Drive.
Here you just embed a JavaScript in your blogger template and it works. Here is the tutorial for you.

Step 1: Go to Dashboard. Then, click Layout.

Step 2: Click HTML/JavaScript and paste the following JavaScript code.

<script language="JavaScript">
<!--

var message="No Right-Click!";

///////////////////////////////////
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>

Step 3: You may change No Right-Click! in any other message. So change it according you choice.
