Removing the link on the slider

Hi,

I have found this page which explains how to alter the code to remove the link on the slider.
http://www.cryoutcreations.eu/forums/t/ability-to-add-more-slides-to-presentation-page

Rather than remove it, I wonder if there is a way to change the link, so I can force a certain post (which appears in the slider only) to link to a page for example?

Any ideas?
