JH Portfolio is a WordPress plugin that adds a portfolio to any WordPress 2.8+ blog.
The plugin has two levels; the pre-made template widgets for ease of use, but for more advanced theme developers it can be used to create complex dynamic portfolios. This website uses the plugin (albeit slimmed down) for the portfolio.
The project’s home is on Google Code and can be found here: http://jh-portfolio.googlecode.com/
