I thought i'd pass this on. I found a free Flash browser that's pretty easy to use, much easier than a custom PS gallery and it's Flash so it's cooler...also has some copy protect advantages over the PS gallery. Anyways I do not work for these guys, but I am changing over my website to use their gallery so I endorse them so far. I've been working with this for about a week.

You can see what I did with the gallerys on my site, most of them are changed over. For comparison's sake the old custom PS galleries still remain in the older MTB galleries so check them out to see the difference. They just seem a lot more slick in comparison.
