Images and Download links not showing on webpage

Hi,
I am using the Preference Lite theme. I have a few images of book covers and download links on a page in my website. Everything shows up properly when I am logged in, but when I or someone else looks at the page it only has one image and no links. I’ve tried with and without tables, I have tried updating and nothing is happening. How do I resolve this? I don’t think the web browser is the problem because it happens on many different browsers.

Thank you.
