Image galleries can be attached to any Django model. And thanks to django 1.1 url namespaces it is possible to have multiple 'albums' app instances (for example, for different models) that use different sets of templates, different permission rules, have dedicated integration test suites and are available from different urls.

Each image gallery provide functionality for image viewing, editing, uploading, reordering, marking/unmarking as main and deleting.

django-photo-albums requires Django >= 1.1 (or svn version with url namespaces), setuptools for installation, django-generic-images for image management and django-annoying.

Sorl-thumbnails should be mentioned as a very good optional dependency for generating thumbnails, but you can use any other library if you want.

Testing if app instance is integrated correctly (at least that templates don't raise exceptions) is easy because base class for integration testcases is provided.
