  The 0.91 branch has an example website that includes a projects_model. In that projects_model we use the on_after_post model hook to further process the image. Below is what that looks like:

  
  function on_after_post($values)
  	{
  		$CI =& get_instance();
  		$CI->load->library('image_lib');
  		
  		// create the thumbnail if an image is uploaded
  		if (!empty($CI->upload))
  		{
  			$data = $CI->upload->data();
  			if (!empty($data['full_path']))
  			{
  				$thumb_img = assets_server_path('projects/'.$this->thumb_name($data['file_name']), 'images');
  				
  				// resize to proper dimensions
  				$config = array();
  				$config['source_image'] = $data['full_path'];
  				$config['create_thumb'] = FALSE;
  				//$config['new_image'] = $thumb_img;
  				$config['width'] = 240;
  				$config['height'] = 140;
  				$config['master_dim'] = 'auto';
  				$config['maintain_ratio'] = TRUE;
  				$CI->image_lib->clear();
  				$CI->image_lib->initialize($config);
  				if (!$CI->image_lib->resize())
  				{
  					$this->add_error($CI->image_lib->display_errors());
  				}
  				
  				// create thumb
  				$config = array();
  				$config['source_image'] = $data['full_path'];
  				$config['create_thumb'] = FALSE;
  				$config['new_image'] = $thumb_img;
  				$config['width'] = 100;
  				$config['height'] = 80;
  				$config['master_dim'] = 'auto';
  				$config['maintain_ratio'] = TRUE;
  				$CI->image_lib->clear();
  				$CI->image_lib->initialize($config);
  				if (!$CI->image_lib->resize())
  				{
  					$this->add_error($CI->image_lib->display_errors());
  				}
  			}
  		}
  
  		return $values;
  	}

  thats great. because of my logical global structure, i want to make that feature accessible to the whole fuel environment. Where do i have to add a hook, to upload predefined image-versions?

  Currently, the above hook is only available on models.

  Does this only work on a single image upload? how would you do this with more than one?
  
  Thanks

  There is an array on the model that holds the uploaded image information called upload_data that you can access from within the on_after_post hook.
