function _createThumbnail($fileName) {
$config['image_library'] = 'gd2';
$config['source_image'] = 'uploads/' . $fileName;
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['width'] = 75;
$config['height'] = 75;

$this->load->library('image_lib', $config);
if(!$this->image_lib->resize()) echo $this->image_lib->display_errors();
}

Call the above function like :

1
$this->_createThumbnail($fInfo['file_name']);

After creation of thumbnail clear the caches.

1
$this->image_lib->clear();

Hope that it will be useful.

Hello, your function needs to know where to save the thumbnail.
$config[‘new_image’] = ‘./thumbs_folder/’ . $fileName;

Thank you!
