当我使用Filezilla上传我的php应用程序时,图像丢失了

I uploaded my php application using Filezilla and when I checked it online, all of the images are missing and total site get break. I don't understand this because everything works fine offline but when I check through after publishing it online, all the images disapear. I also checked all my links and they're fine.

Here is my code

<html>
<head>
   <title> Vatsal Technosoft Messanger </title>
   <script type="text/javascript" src="../JavaScript/frmvalidation.js"></script>
   <link href="../Stylesheet/style.css" media="all" type="text/css" rel="stylesheet" />
</head>
<body> 
   <?php include 'connect.php' ?>
   <?php include 'functions.php' ?>
   <?php include 'header.php' ?>

   <div id="outer" style="margin-top:0px;">
      <div class="container" style="color:#00C; z-index:1;">

        <div class="subcontainer" >
        <?php

          if(loggedin())
          {

         ?>
         <a href='' onclick='addcontact();' id='noti' style='text-  decoration:none;margin-bottom:0px;'>
         <?php
            $my_id = $_SESSION['user_id'];
        $notifrnd = mysql_query("SELECT * FROM `frnd_req` WHERE `to` = '$my_id' ");
        if(mysql_num_rows($notifrnd))
        {
          while($arr = mysql_fetch_array($notifrnd))
      {
             $fid = $arr[1];
         $firstname = getfirstname($fid , 'firstname');
         $lastname = getlastname($fid , 'lastname');
     }
     echo "<font style='color:#FFFF00; font-size:11px; margin-left:15px; margin-top:3px; margin-bottom:5px;  float:left; font-weight:bold;'>You have Friend request</font>";

        }
       }
        ?>
     </a>
