Add fitToSquare function to SimpleImage class, this functions calculate the x and y coordinates of the source image, then crop as square. I haven't test my function:) But it seems ok.

   function fitToSquare($width) {
      $new_image = imagecreatetruecolor($width, $height);

      $sourceX = 0;
      $sourceY = 0;

      if($this->getWidth() > $this->getHeight())
      {
          $sourceX = ($this->getWidth() - $this->getHeight()) / 2;
      }
      else
      {
          $sourceY = ($this->getHeight() - $this->getWidth()) / 2;
      }

      imagecopyresampled($new_image, $this->image, 0, 0, $sourceX, $sourceY, $width, $height, $this->getWidth(), $this->getHeight());
      $this->image = $new_image;
   }
