About sidebar position

I try to use this theme on my blog. Thank you for the awesome works.
I want to show big pics in my post, so I delete the sidebar. However, I need the three or four column navigation in the bottom of the site. Now it looks like that in this address:http://sweetblues.org/ after I inserted a DIV in the footer.php. I can provide more information later if anyone need. Thanks.

You have completely broken theme layout therefore I can’t help you with that. It will be much easier to just reinstall this theme entirely that trying to find what you did wrong.
