How to disable the right mouse button on images (Opera)

Hey, I am able to disable the right mouse button on images for netscape
and IE but it won't work for Opera.

Here is the code:

// start of the code

var clickmessage="Sorry, you don't have permission to right-click."

function protectImages () {
if (document.all)
document.oncontextmenu=disableclick
else if (document.getElementById)
document.oncontextmenu=disableclick
else if (document.layers)
associateimages()
}

function disableclick(e) {
if (document.all) {
if (event.srcElement.tagName=="IMG"){
alert(clickmessage);
return false;
}
}
else if (document.layers) {
if (e.which == 3) {
alert(clickmessage);
return false;
}
}
else if (document.getElementById){
if (e.target.tagName=="IMG"){
alert(clickmessage)
return false
}
}
}

function associateimages(){
for(i=0;i<document.images.length;i++)
document.images[i].onmousedown=disableclick;
}

// end of code ----

My question is:

How do I make the code work for Opera 7.x?

Thanks in advance.

Good. That is one of the reasons I like Opera.

My reply to getting a message like that, would be ... not printable in
a public forum.

Give up. Whatever you are trying to do, it won't work against anybody
with half a clue. If you don't want people to save your images, don't
put them on the web.

You are not supposed to be able to interfere with my browsers
interface.
If you find a way, please tell us, so we can have the bug fixed.

My point is not whether I will annoy visitor or not, but whether I can
do it or not technically with Opera.

My point is not whether I will put the iamges on net or not, but whether
I can do it or not technically with Opera.

The answer to that was no. With an attached "luckily".
