loading issue after logout

Hi guys,

Im currently working on a project that has member system.
At home page will appear some images from Database and the directory.
The issue is once i logout the page will redirect to home page but the images won't load and i can see the images are missing.

Im testing on my localhost.
Is the issue about my code?

Here is my logout function:

PHP Code:

function logout()
    {
        $this->session->sess_destroy();
        $this->cart->destroy();

        redirect('/');
    } 


Any idea?

Thanks
