Moa is an image gallery website system written in PHP and using MySQL for data storage. It is released as Open Source under the zlib/libpng license. This allows pretty much any usage as long as you don't claim that you wrote it.
The intended use is for websites that want a gallery but do not want the complexity and extended feature set of some of the heavier-duty open source galleries. It is purposefully designed to not require registration/login (apart from admins), has no comments/ratings and provide just one shared set of galleries. Our reasoning for these is that someone putting up pictures of their pet or holiday on a personal homepage usually won't care about feedback.
However that doesn't mean the site-owner doesn't need decent tools and we provide some of these (with more to come). "Tags", or keywords, are given to all galleries and images and are the way the site knows where to put each image. This allows a hierarchical gallery structure and allows images to appear in more than one gallery without re-uploading. Galleries can be made and will auto-populate with any images that have matching tags. Adding, editting and deleting galleries/images is easy.
