Site update, and why image previews aren't working

Hello all, NBB here. As you may or may not be aware, we've been dealing with an ongoing spam attack here. The problem does not affect you, the reader nor your computers; it's an exploit designed to screw around with our rankings in search engines.

As part of trying to fix this problem, I've had to make some changes to how the site works on the back end. One effect of this is that image previews aren't working right now.

Thank you for your patience.
