You can do this with the codeigniter image manipulation class.

Just create a helper with your image resize code, here is a basic example:

In the Helper

if ( ! function_exists('generate_image'))
{
    function generate_image($img, $width, $height){

        $obj =& get_instance();

        $obj->load->library('image_lib');
        $obj->load->helper('url');

        $config['image_library'] = 'gd2';

        $config['source_image'] = $img;
        $config['new_image'] = './resources/images/img_tp/tn_img.png' ;
        $config['width'] = $width;
        $config['height'] = $height;

        $obj->image_lib->initialize($config);

        $obj->image_lib->resize();

        return $config['new_image'];
    }
}

Name as you wish and ensure to load the helper in your controller constructer.

Then in your view:

You can create a set of functions in the helper to perform different manipulation tasks and use them directly in your view using this method.

Here is the image manipulation documentation. http://codeigniter.com/user_guide/libraries/image_lib.html

So will do parallel list of all found libs. Maybe you will need it.

1. Elliot Haughin’s Codeignuter Multicache Library (memcache , PHPCache) download
2. Khaos::Khcache(eAccelerator, APC und XCache)  download
3. Cache Library (memcache, file)    download

Add some more in comments if you know

1) Run mysql query from /addon_folder/install.sql

2)read /addon_folder/readme.txt

3)upload /addon_folder/application  to the /system folder of his web-site or wherever the application folder he put , and don’t worry that anything will be overwritten

4) in case there should be any hacking made to the system files, like config.php, routes.php or else , ther should be  very well described

/addon_folder/hackit.txt you do what is written, and  yummy!

5) YOU GO to mysite.com/addon/ and feel happy! Everything should work!

I will add the rules step by step here. Your comments will be very appreciated

So  I am begining to add .

1) The addon should have  DBAD License (Don’t Be A Dick)

$this->db->insert_id();

Note: Helper uses php  php function mysql_insert_id

Note2:

Retrieves the ID generated for an AUTO_INCREMENT column by the previous query (usually INSERT).

Have Fun.

http://wiki.codeigniter.ch/wiki/ci-wiki/OEmbed-Library

Библиотеку OEMBED для codeigniter.

ставим ее в папку /application/libraries/

и юзаем так: Либо делаем автолоад библиотеки в

/application/config/autoload.php

либо в самом коде делаем так

1 $this->load->library('oembed');

а там 


1 $params = array('type' => 'xml', 'cache' => TRUE);
2 $this->load->library('oembed', $params);

Имейте ввиду что не все провайдера дают возможность параметров. 

потом можно инфо про видеофайле узнать таким способом

Youtube

Как видите в списке есть не только видеосервисы. Так что дерзайте. Если вы не виагру рекламируете, то задавайте вопросы в коментах. Отвечу...

6 $this->oembed->call('youtube', 'http://www.youtube.com/watch?v=nKu60YKqsvs&feature=rec-LGOUT-exp_stronger_r2-HM');

Качаем сначала KhCache (http://codeigniter.com/forums/viewthread/69843/) от  Khaosа.

1. Инсталл

Кидаем его в папку /application/libraries/

И начинаем юзать.

Если захотите переписать дефолтовые значения , те параметры библиотеки, то в папке /application/config создаем Khaos.php

И в нем пишем

$config['cache'] = array('container' => 'File',
                         'ttl'       => 3600,
                         'File'      => array('store'           => BASEPATH.'cache/',
                                              'auto_clean'      => 10,
                                              'auto_clean_life' => 3600,
                                              'auto_clean_all'  => false));

Все думаю понятно. Если захоите вместо контейнера File  использовать скажем XCache Надо немножко помудить
с библиотекой

А в конфиге Написать так например

 $config['cache'] = array('container' => 'APC');  

Для чего отвечают отдельные ключи в массиве? 

auto_clean - By default there is a 1 in 10 chance of the cache dir being cleaned, set to false to disable.
 auto_clean_life - Files older than this will be removed.
 auto_clean_all - By default only cache files prefixed with khcache_ are removed set to true to have khcache clean the entire directory
2. Использование

Для того чтоб использовать

$this->khcache->generatekey(): Делает Идентификатор Кеша чтоб потом мы смогли достать его.
$this->khcache->store($key, $data, $ttl): Сохраняет  ($data) под идентификатром ($key) на время $ttl секунд  в Кеш.
$this->khcache->call($func, $args, $ttl): Делает функцию  ($func) с аргументами ($args, Typ: Array) и сохраняет  ответ на $ttl Секунд в кеш.
$this->khcache->fetch($key):Читает элемент информации, который под ключом $key спрятан в кеше.
$this->khcache->delete($key): Удаляет элемент информации под ключом $key из кеша.
$this->khcache->delete_all($key): Удаляет все элементы из Кеша.
$this->khcache->get_hits(): Дает все успешные вызовы функции кеша  (Benchmarking).
$this->khcache->get_misses(): Дает количество безуспешных вызовов  (Benchmarking).


Надеюсь Понятно перевел.
