First I want to say that I really like the concept of the Flash Gallery. It is easy to use and set up in such a way that my clients can use it with little training. I have a few opinions/suggestions that i think would make the script better.

First, I think the Flash Gallery script should take on more of the form of a slide show than it already is. Features like playback control (automatic playback, forward, previous, pause) would be helpful.

Second, I think that there could be more customization available for the look of the Flash Gallery.

That's all I can think of for the moment. I really like all your scripts and I hope that you find my ideas helpful.
