OK, I know what the problem is now. I don't see the amazon box because I use Mozilla Firefox as my browser (as do many people). Ads are blocked so I need to allow them on this site in order to see them, which I just did and now I see the pictures and the links work perfectly. Had I seen them originally it certainly would have made sense. Maybe you could add a message to Firefox users to disable their adblock for this website.
Thanks, now I can order through the Pool Forum!!
