Home Page Slider Issues

Hi, I'm having a couple of problems with the featured slider images please see www.volitionremovalslondon.com . Currently I have set up three featured images on posts. When I am on the homepage on the live site if I click on the slider image I go to a page that says "oops that page can't be found" and if I click on the post title within the slider it takes me to the post. Ideally I would like the featured image to be driven from my main content pages and then if one were to click on the image or the title in the slider it would take them to the appropriate page. That said the image doesn't appear to link to properly to the post. The second option I can see is to make the slider image and the title text non clickable. Please can someone help with a solution to either?
