Here is a list of very simple plugins you can use with LocalFilesEditor.

On thumbnails list, if you have severals items, you may want to display the navigation bar on the top in addition to the bottom one.

<?php
/*
Plugin Name: Navbar on top
Version: 1.0
Author: Mistic
Author URI: http://www.strangeplanet.fr
*/
 
add_event_handler('loc_end_index', 'top_navbar');
function top_navbar()
{
  global $template;
  $template->set_prefilter('index', 'top_navbar_prefilter');
}
function top_navbar_prefilter($content, &$smarty)
{
  $search = '{if !empty($CATEGORIES)}{$CATEGORIES}{/if}';
  $add = '{if !empty($navbar)}{include file=\'navigation_bar.tpl\'|@get_extent:\'navbar\'}{/if}';
  return str_replace($search, $add.$search, $content);
}
?>

<?php
/*
Plugin Name: Remove breadcrumb photocounter
Version: 1.0
Author: barbichou
*/
 
add_event_handler('loc_end_index', 'no_breadcrumb_counter');
function no_breadcrumb_counter()
{
  global $template;
  $s = $template->get_template_vars('TITLE');
  $pos = strrpos($s,"[");
  if ($pos !== false)
  {
    $template->assign('TITLE', substr($s,0,$pos));
  }
}
?>

This plugins displays only the last album name in page title, not the full tree.

<?php
/*
Plugin Name: One level in page title
Version: 1.0
Author:barbichou
*/
 
add_event_handler('loc_end_page_header', 'one_level_pagetitle');
function one_level_pagetitle()
{
  global $template, $conf;
  $titre = $template->get_template_vars('PAGE_TITLE');
  $pos = strrpos($titre, $conf['level_separator']);
 
  if ($pos!==false)
  {
    $template->assign('PAGE_TITLE', substr($titre, $pos+strlen($conf['level_separator']))); 
  }
}
?>

This plugin allows to give URL with a additional parameter witch will force the current theme. For exemple : http://mysite.com/picture.php?/246/category/186&temp_theme=Stripped will open this picture page with the theme Stripped whatever is the default theme. Only works for picture page.

<?php
/*
Plugin Name: Theme Switch From URL
Version: 1.0
Author: Mistic
Author URI: http://www.strangeplanet.fr
*/
 
add_event_handler('user_init', 'theme_controler_lite1');
add_event_handler('init', 'theme_controler_lite2');
 
function theme_controler_lite1()
{
  global $user;
 
  if ( isset($_GET['temp_theme']) and file_exists(PHPWG_THEMES_PATH.$_GET['temp_theme']) )
  {
    $user['theme'] = $_GET['temp_theme'];
  }
}
function theme_controler_lite2()
{
  global $template;
 
  if ( isset($_GET['temp_theme']) and file_exists(PHPWG_THEMES_PATH.$_GET['temp_theme']) )
  {
    $template->assign('TEMP_THEME', $_GET['temp_theme']);
    $template->set_prefilter('picture', 'theme_controler_lite_prefilter');
  }
}
function theme_controler_lite_prefilter($content)
{
  global $conf;
  if ($conf['question_mark_in_urls']==false)
  {
    $search = '#(action|href)="([^?"]*)"#';
    $replace = '$1="$2?temp_theme={$TEMP_THEME}"';
  }
  else
  {
    $search = '#(action|href)="([^"]*)"#';
    $replace = '$1="$2&amp;temp_theme={$TEMP_THEME}"';
  }
 
  return preg_replace($search, $replace, $content);
}
?>
