background images not showing

I’ve just finshed my first WordPress installation and none of the bg images show on the index page and not in Presentations > Themes in the backend either.

My blog is running on https://www.afogtil.com and I’m on a WinXP box with both IE6 and Firefox1.5. I’ve tried on multiple pc’s.

I’ve looked at some of the previous posts about the same problem but none suggest a resolution.

I’ve been running Joomla and Nucelus on this server before without any background img problems so I’m hoping someone can help !
