I'm using NGG v. 0.99 and WP 2.6.5
I would have upgraded both however I've made way too many theme changes to warrant doing it all over again for the time being. Keep in mind, theme changes are 99% cosmetic so nothing that I've done in the past should really affect this Plug-in.
I installed NGG, added a gallery, added some photos and picked a random post to add my [gallery=1] shortcode to. I was expecting a few thumbnails but instead all I got was the image browser. I've not made ANY changes to the default NGG settings thus far.
... am I doing something wrong? Or am I missing something?
Here's a link to my example (pardon the bad break after the post)
