Zoph (Zoph Organizes Photos) is a web based digital image presentation and management system. In other words, a photo album. It is built with PHP and MySQL. You can run it on your own server, but it's also compatible with most webhosting solutions.
Many people store their photos in the digital equivalent of a shoe box: lots of directories with names like 'Holiday 2008', 'January 2005' or even 'Photos034'. Like shoe boxes, this is a great way to put your photos away, but not such a great way to find them back or even look at them. Zoph can help you to store your photos and keep them organized.
While most photo album projects are primarily targeted at showing your photos to others, Zoph is primarily targeted at keeping your photos organized for yourself, giving you granular control over what you'd like to show to others, on a per-album or even a per-photo basis.
If you just want to generate a gallery of thumbnails from a bunch of images, you may want to try one of the other numerous photo album projects. But if you want to also store additional information about your photos, search them, or control access to them, take a look at Zoph.
