What is the best fully interactive photo and video gallery package to use on a website?

I’m making a site where there will be many different groups all with their own password protected gallery. I’ve played with gallery 1 and 2 from Menalto and was wondering if there is just a packaged software program I could upload to the site.–Thanks
Purchasing a package is acceptable, it doesn’t necessarily have to be freeware.

Gallery 1/2 is already on a Paid hosting site. It’s in the Control Panel ready to be installed and is free. For others…
