Gallery 2
Open-Source
If you manage a Web site—be it a personal or community site, either on your own server or a hosted service—Gallery 2 is a great tool for organizing photos and integrating them into the site. Create and manage albums, upload photos, set permissions, and much more.
For the moment, use XAMPP or (much smaller, not bloated) MicroApache (for Gallery2, you'll want the distribution with GD). I'm working on a PortableApps.com implementation of MicroApache, but it's not ready yet. MicroApache does work well from a USB disk, though.
I am a Christian and a developer and moderator here.
