Free Gallery Scripts

I needed an image gallery for a website I was developing. After searching for a while I got three that, in my opinion, are the coolest ones around. I wanted something easy to create multi-galleries which also offered transitions and some other cool effects. Of course I was looking for a free alternative. Open-source rocks! I always look for scripts using Ajax and Mootools because they are light and have great visual effects. But since nobody knows it all and in order to make this list more efficient, I’d like YOU to make recommendations, I will add them to the links.

1. SmoothGallery 2.0 – Allows you to have a set of galleries. This feature alone made me select it, because we will need a multi-gallery website.
2. Webtwo Ajax SlideShow – It let’s you zoom the freaking picture!! It adds a real professional look to your website..
3. (E)² Photo Gallery Made With Mootools – I almost chose this one for the second section of the website. It has a cool slider under it.
