<h3>Overview</h3>
This plugin allows you to create Wordpress photo galleries from any Facebook album you can access.<br /><br />
To get started, you must first connect with your Facebook account using the button below. Once connected, you can create a gallery by making a new Wordpress post or page and pasting in one line of special HTML, like this:<br /><br />
<b><!--<?php
echo $fpf_identifier;
?>
1234567890123456789 --><!--/<?php
echo $fpf_identifier;
?>
--></b><br /><br />
Whenever you save a post or page containing these tags, this plugin will automatically download the album information and insert its contents between them. You are free to include any normal content you like before or after, as usual.<br /><br />
The example number above (1234567890123456789) is an ID that tells the plugin which Facebook album you'd like to import. To find a list of available albums, you can use the "Search for Albums" feature under the "Utilities" tab.<br /><br />
That's all there is to it! For more information on how to customize your albums, help, and a demo, please see the full documentation on the <a href="<?php
echo $fpf_homepage;
?>
"><b>plugin homepage</b></a>.<br /><br />
And if you like this plugin, please don't forget to <a href="javascript:void(0);" onclick="fpf_swap_tabs('<?php
echo $tab4Id;
?>
');jQuery('html, body').animate({ scrollTop: jQuery(document).height() }, 'slow');"><b>donate</b></a> a few bucks to buy me a beer (or a pitcher). I promise to enjoy every ounce of it :)<br /><br />

<h3>Refresh Albums from Facebook</h3>
This will scan all your posts and pages for galleries created with this plugin,
and regenerate each one it finds by re-fetching its information from Facebook.
The only reason to use this would be if you've changed or updated something in many of your albums and want those changes to be reflected here as well. It can be slow if you have lots of galleries, so use with caution.<br /><br />

<h3>Donate</h3>
Many hours have gone into making this plugin as versatile and easy to use as possible, far beyond my own personal needs. Although I offer it to you freely, please keep in mind that each hour spent extending and supporting it was an hour that could've also gone towards income-generating work. If you find it useful, a small donation would be greatly appreciated.
