Here you can see some JFBAlbum demo.
This page contains only Modules at different module positions. You can also use this extension as a component and embed modules inside an article. For component demo use the menu on the right column. The Gallery View is a 2 level view of all the albums (max 28) from a fan page (Gallery view is for fan page only... no personal album)
To purchase the extension go to the main site (link is on the top right corner)
