$uploaddir = "photo/";
$uploadfile=$uploaddir.$_FILES['photosrc']['name'];
            if (move_uploaded_file($photosrc, $uploadfile)) {
   
            $newSize = 400;
            $src_img = imagecreatefromjpeg($photo_dir.$_FILES['photosrc']['name']);
            $imginfo = getimagesize($photo_dir.$_FILES['photosrc']['name']);
            $srcWidth = $imginfo[0];
            $srcHeight = $imginfo[1];
            $ratio = max($srcWidth, $srcHeight) / $newSize;
            $ratio = max($ratio, 1.0);
            $destWidth = (int)($srcWidth / $ratio);
            $destHeight = (int)($srcHeight / $ratio);
            $new_w =  $destWidth;
            $new_h = $destHeight;
            $dst_img = imagecreate($new_w,$new_h);
            imagecopyresized($dst_img,$src_img,0,0,0,0,$new
_w,$new_h,imagesx($src_img),imagesy($src_img));
            imagejpeg($dst_img, "$uploaddir"."thumb/".$_FILES['photosrc']['name']);
