Ho un problema con il caricamento delle foto, insommo se scatto una foto con verticale me la ruota automaticamente, pero per il resto funziona benissimo, qualcuno può aiutarmi ?

il problema lo riscontro principalmene sui thumb ovvero le anterprime, ovvero tutti i file salvati (nome file)t.png/jpg/gif
PHP:
<?php
   $dir_img = '../img/user_img/';
   header('Cache-control: max-age='.(60*60*24*365));
   header('Expires: '.gmdate(DATE_RFC1123,time()+60*60*24*365));
   if (isset($_GET['img']) AND file_exists($dir_img.$_GET['img'].".png")) {
       if (isset($_GET['t'])) {
           $type = exif_imagetype ($dir_img.$_GET['img'].".png");
           $thumb = $dir_img.$_GET['img']."t.png";
           $thumboriginal = $dir_img.$_GET['img']."t.png";
           
           if (!file_exists($thumb)) {
               if ($type==1) {
                   $im = $dir_img.$_GET['img'].".png";
                   list($width, $height) = getimagesize($im);
                   $im = imagecreatefromgif($im);
                   if ($width > $height) {
                     $y = 0;
                     $x = ($width - $height) / 2;
                     $smallestSide = $height;
                   } else {
                     $x = 0;
                     $y = ($height - $width) / 2;
