I’ve added a gallery using the WPG2 plug-in for wordpress in combination with the freeware php gallery2 application. It took some serious wrangling and config but I think it looks good and works really well.
There is supposed to be a way for guest to make comments on the pictures but it doesn’t seem to be working through WordPress (only if you view the gallery natively using this link)
I’ve also added a subscription feature so if you enter your email address in the box in the sidebar you’ll get an email when I make a new post on the site.
