This WordPress plugin will help integrate your Gallery (gallery.sf.net) albums and photos into your WP blog.
This plug was inspired by the MT plugin GalleryLink and the Blosxom galleryref plugin. Please make sure to edit the WPG_GALLERY_BASE and WPG_ALBUM_BASE bits below or use the WP-Plugin Manager.
