Como poner un Slideshow

Muchas veces he querido poner una presentación en mi blog pero no he sabido como hacerla, hasta hace unos días.
El sistema que he encontrado se llama Nivo, y funciona con la libreria jQuery que hay que agregarla. Si ya la tenéis en vuestra plantilla, no hará falta ponerla otra vez.
Aquí os dejo un vídeo tutorial del proceso y todos los códigos que necesitáis. Espero que os sirva!


Primer código:
<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js' type='text/javascript'/>

Segundo código:
<script type='text/javascript'>
