When image_width > 700 then thumbnail is not created.

So how this part

if($data['image_width'] > 700)
	            {
		            
		            $task = $this->image->image_resize_for_gallery('./uploads/gallery/'.$this->input->post('album_folder').'/'.$data['file_name']);
		            if($task != 'ok')
		            {
		            	echo $task.':err';	//pagal galune .err javasctriptas atskirs kad cia klaida
		            }
		            
	            }

can change anything? It looks that it just does what it has to do - makes image smaller. And I made console.log in javascript and it does not show any error..

Nothing fancy in image resize function:

function image_resize_for_gallery($source_image)
	{
		
		$config['image_library'] = 'gd2';

		$config['source_image'] = $source_image;
		$config['maintain_ratio'] = TRUE;
		$config['width']	 = 534;
		$config['height']	= 700;
		
		$this->load->library('image_lib', $config); 

		if ( ! $this->image_lib->resize())
		{
			return $this->image_lib->display_errors();
		}
		else return 'ok'; 
	}
