    Its a simple typo I am afraid. You just missed a ; after the first echo and missed the echo command on the last line that outputs the last div

    While developing a script it is a good idea to make sure you have error reporting turned on.

    <?php 
        // turn on error reporting while developing a script
        ini_set('display_errors', 1); 
        ini_set('log_errors',1); 
        error_reporting(E_ALL); 
        mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
    
        echo"<div class='vod'>";
        // missing semi colon  ^
    
        $con = mysqli_connect ("localhost","root","","demo");
        $id = @addcslashes ($_REQUEST['id']);
    
        $image = mysqli_query($con,"SELECT * FROM img WHERE id= '$id'")
                or die(mysqli_error($con)); 
        $image = mysqli_fetch_assoc ($image); 
        $image = $image['img'];
    
        header ("content-type: image/jpeg"); 
        echo $image;
    
        echo "</div>";
    //  ^^^^ the echo here was also missing
    ?>
    

    Note: You should also use prepared parameterised queries to protect your scripts from SQL Injection Attacks
