I get a lot of client requests for some sort of gallery plugin and it is clear to me now that the best gallery plugin for WordPress is: NextGen Gallery. The user interface is easy to use, the plugin is actively being developed, there are lots of options for the users, and it is a joy to work with. Out of the box it comes with a widget to load in recent or random images in your sidebar (or page) as well as an easy way to display single galleries or multiple galleries (albums). This is a must have for anyone who is looking for an elegant solution to display images.
