Some weeks ago, I wanted to add a slider to my wordpress theme. At first, the slider was reading data from custom meta boxes at posts from the wordpress cms, and was linked to posts, but this had reduced flexibility since it was not possible to link a slider to any post, page or item. The solution? Use custom posts or custom content that is used for the slider only. This tutorial describes how to set up custom post types yourself, and to add a jquery slider that uses these custom post types, both in a wordpress environment. It is assumed that you have basic understanding of wordpress and understand html and css well.
