Question: I need a working script for prohibiting users from saving images on their machine. (Is it only possible through disabling right-click?)
Yes, I know that it is impossible, and yes I know that it is a bad practice.
Yes, I also know that I am an idiot. But I need this solution for some specific purposes.

Thanks!

Answer: 
the only real way to do it is probably to encrypt the images in a flash file or something, but no matter how much time you spend jumping through hoops the user can still just press printscreen. there is no reason to even try doing this.

```
<body oncontextmenu="return false;"> 

```

Or...

```
document.body.oncontextmenu = function(){
    return false;
}

```
