Image catalog: make archives of photographs more accessible.
This is the core part, containing the models. The crawler/updater, web frontend/gallery and more projects will depend on it.
As a (hobby) photographer, you might have years and many gigabytes of material on your drives which you only rarely watch back. To make it more easy to find certain pictures or just provide a fun trip down memory lane, use imagine to make an overview of your archives.
The goal is not to import the images into a (new) archive and manage collections from there, but to provide an easy-to-use overview of your work. This can even be used standalone (think on a different machine with no access to your library).
