view image without true url

How can I view image using code like

Echo "<img src='image.php?image=12'>";

what is the code of image.php to do that ?

There is no code to do that.

PHP Code:

---

if(isset($_REQUEST['Image'])){
switch($_REQUEST['Image']){
    case "1":
        header("Content-type: image/gif");
        $filename = "images/one.gif";
        $fp = fopen($filename,"r")or die("Something went wrong :S");
        while(!feof($fp)){
        $chunck= fread($fp,16);
        print $chunck;
        }
    break;
    case "2":
        header("Content-type: image/gif");
        $filename = "images/two.gif";
        $fp = fopen($filename,"r")or die("Something went wrong :S");
        while(!feof($fp)){
        $chunck= fread($fp,16);
        print $chunck;
        }
    break;
}
}

you could kinda do the same if you were reading the data from a database.
