makeSlider({url:"URL DE TU BLOG"});

Ahora solo tienes que reemplazar la URL de tu blog donde se indica y listo, guarda los cambios y a disfrutar de este genial truco.

Al agregar la URL de tu blog te en cuenta que la tienes que agregar así: http://www.miltrucosblogger.info sin la ultima barra inclinada / ya que si la agregas el truco no funcionara.

Espero que les sea de utilidad este truco y sigue visitando Mil Trucos Blogger.
