Flickr is a great solution for managing your photos, but it can be a bit tough to show those photos on your site.
This plugin provides an easy method to display your Flickr sets & photos on your site. You can put custom CSS in your theme’s stylesheet to redefine the look and feel of your galleries.
You can also choose to not display ‘private’ photos on your site, or to not show certain albums.
