Use the following script

<?php
     
    require 'connect.php';
    $userg = mysql_query("SELECT avatar FROM members")
    or die("Failed to fetch your details.");
     
    if (isset($_SESSION['MM_Username'])){
    echo "Welcome ".$_SESSION['MM_Username'];
?>

<img src="<?php echo mysql_result($userg,0,"avatar" ); ?>" width="50%" height="50%">


<?php
    
     
    }
    ?>
