<?php
include('confi.php');
/**********MYSQL Settings****************/
function GetImageExtension($imagetype)
     {
       if(empty($imagetype)) return false;
       switch($imagetype)
       {
           case 'image/bmp': return '.bmp';
           case 'image/gif': return '.gif';
           case 'image/jpeg': return '.jpg';
           case 'image/png': return '.png';
           default: return false;
       }
     }
if($_SERVER['REQUEST_METHOD'] == "POST"){
if (isset($_FILES["file"]["name"])) {
    $file_name=$_FILES["file"]["name"];
    $temp_name=$_FILES["file"]["tmp_name"];
    $imgtype=$_FILES["file"]["type"];
    $ext= GetImageExtension($imgtype);
