Now there's an easy way to embed custom Facebook galleries in your WordPress installation from your profile or pages!
That feature is on its way and is planned for the next release!
The point of this plugin, stylistically, was to create a barebones class structure that you can build on accordingly. The way to add styles (currently) is to add them in your theme's stylesheet. In the next release, I plan to allow for you to drop in custom styles of your own.
They aren't in this release, they will be in future releases. Truth be told, they weight down load times enough, but they can indeed be implemented.
The plugin has to get information from Facebook, it could be downloading 200 images from their servers in a matter of seconds. The fact that it happens as quick as it does is somewhat of a miracle. No worries though, I have plans to optimize the front-end of the plugin in the future to allow AJAX loading of photos... this way your page will load and images will then pop in as they're downloaded from Facebook's servers.
