Removing link in presentation page slider

I have searched the forums for an answer to this but can’t find anything.
I wanted more than 5 images in the slider so I used the “random from catagories” feature and made posts with the individual images and marked them as featured. Now I have phantom link to either just the image as a post (when I titled the post) or “Apologies, but the page you requested could not be found. Perhaps searching will help.” (when I didn’t give the post a title). How can I get rid of the link? I just wanted more than 5 images…
