<?php defined('syspath') or die('no direct access allowed.');  class uploader_controller extends controller_core {  public function bulkupload() {     kohana::log('debug', 'start upload');     $files = validation::factory($_files)                     ->add_rules('picture', 'upload::valid', 'upload::required', 'upload::type[gif,jpg,png,jpeg]', 'upload::size[10m]');     kohana::log('debug', 'start validate');     if ($files->validate()) {         kohana::log('debug', 'validate passed');          $filename = upload::save('picture');         $thumbsize = kohana::config('upload.thumb_size');          image::factory($filename)                 ->resize($thumbsize[0], $thumbsize[1], image::width)                 ->save(docroot . 'assets/media/thumbs/' . basename($filename));          $partname = explode('/', $filename);         $picture = $partname[count($partname) - 1];         $data['name'] = '';         $data['picture'] = $picture;         $data['category_id'] = $this->input->post('category_id', 0);         $data['description'] = '';         ;         $data['user_id'] = $this->input->post('user_id', 0);         $picturemodel = new picture_model();         try {             $photo = $picturemodel->savepicture($data);             echo url::site('assets/media/' . $picture);         } catch (exception $e) {          }     } } }

i have add line still not working:

$filename->resizetowidth(300);

you not using kohana image , upload library properly. docs have examples on how use kohana image upload , resize library:

you can resize , save image following code:

image::factory($filename)     ->resize(300, null, image::auto)     ->save($your_save_path);
