Thanks to 509tyler, I got on the right track, the links in this plugin are indeed broken but can be restored. Edit facebook-photos.php and change link 31 to 33:
<script type='text/javascript' src='".get_bloginfo('wpurl').'/wp-content/plugins/facebook-photos/jq-lightbx/js/jquery.js'."'></script>
<script type='text/javascript' src='".get_bloginfo('wpurl').'/wp-content/plugins/facebook-photos/jq-lightbx/js/jquery.lightbox-0.5.js'."'></script>
<link rel='stylesheet' type='text/css' href='".get_bloginfo('wpurl').'/wp-content/plugins/facebook-photos/jq-lightbx/css/jquery.lightbox-0.5.css'."' media='screen' />
to
<script type='text/javascript' src='".get_bloginfo('wpurl').'/wp-content/plugins/facebook-album-photos/jq-lightbx/js/jquery.js'."'></script>
<script type='text/javascript' src='".get_bloginfo('wpurl').'/wp-content/plugins/facebook-album-photos/jq-lightbx/js/jquery.lightbox-0.5.js'."'></script>
<link rel='stylesheet' type='text/css' href='".get_bloginfo('wpurl').'/wp-content/plugins/facebook-album-photos/jq-lightbx/css/jquery.lightbox-0.5.css'."' media='screen' />
With other words: the directory in the links is wrong, it should be facebook-album-photos in stead of facebook-photos
After the change, it worked with no problem!
good luck!
