The reason I'm showing a jAlbum is to demonstrate you can load pages without going through the controllers - well, sort of !
The jAlbum application is in it's own directory (i,e. the one produced by jAlbum when the album was made. This contains all the pictures, thumbnails, style sheets and images used to build the jAlbum container.
There's a normal CI page routed in the usual way. The jAlbum application is in an iFrame on this page. The path to the jAlbum folder is made by concatenating base_url() to the path from the CI root to the jAlbum folder. If we change URLs for the site the page will still work.
The pictures are a random collection taken about 8 years ago (2007) using a variety of cameras.
