									  private $d_height;

									  private $d_width;

									  private $name;

									  public function thumb($image_path,$rate = 0.5){

									    $this->src = $image_path;

									    $this->source = imagecreatefromjpeg($image_path);

									    $s_size = getimagesize($image_path);

									    $this->s_height = $s_size[1];

									    $this->s_width = $s_size[0];

									    $this->d_height = 100;

									    $this->d_width = 100;

									    $this->dest = imagecreate($this->d_width, $this->d_height);

									    $this->name = explode('.jpg', $image_path);

									    $this->name = $this->name[0];

									  }

									  public function make(){

									    imagecopyresized($this->dest, $this->source, 0, 0, 0, 0, $this->d_width, $this->d_height,

									    $this->s_width, $this->s_height);

									    $thumb = str_replace('image', 'thumb', $this->name.'-thumb.jpg');

									    imagejpeg($this->dest,$thumb,100);

									    $img = $thumb;

									    echo "<a href=$this->src><img src=$img></a>";

									  }

									}

									$hl = opendir(".\\image\\");

									while(false != $file = readdir($hl)){

									  if($file == '.' || $file == '..') continue;

									  $path = '.\\image\\'.$file;
