copyImageFile('avatar1', $sTempFileName, 500, 500);
copyImageFile('avatar2', $sTempFileName, 700, 700);

zastąp ten kod po

     include('connect/mysql.php');
    $avatar1=copyImageFile('avatar1', $sTempFileName, 500, 500);
    $avatar2=copyImageFile('avatar2', $sTempFileName, 700, 700);
$user_name = mysqli_real_escape_string($con, $_SESSION['UserName']);

       mysqli_query($con,"UPDATE profiles SET AvatarImage='".$sResultFileName."',AvatarImageBig='".$avatar1."',AvatarImageSmall='".$avatar2."' WHERE UserName = '$user_name'");   
        mysqli_close($con);
