+<h2>Edit a category</h2>
+
+<h3>Informations</h3>
+
+<ul>
+
+  <li><strong>name</strong>: rename the category (a virtual rename in case 
+  of physical category).</li>
+
+  <li><strong>description</strong>: give a general idea of the content,
+  this text will be display under the thumbnail page.</li>
+
+</ul>
+
+<h3>Move</h3>
+
+<p>If the category is virtual, you can move it. Moving a category means
+changing its parent category.</p>
+
+<h3>Options</h3>
+
+<ul>
+
+  <li><strong>Access type</strong>: Permission management. If you make a
+  category private, all its child categories becomes private. If you make a
+  category public, all its parent categories becomes public.</li>
+
+  <li><strong>Lock</strong>: The category and its sub-categories will
+  temporary been disabled for maintenance.</li>
+
+  <li><strong>Comments</strong>: Authorize users to comment elements of this
+  category.</li>
+
+  <li><strong>Authorize upload</strong>: Authorize users to upload
+  files. This option is available only if category is physical (not
+  virtual).</li>
+
+</ul>
+
+<p>You can also manage these options with "Properties"
+management screen (screens <span class="pwgScreen">Upload</span>, <span
+class="pwgScreen">Comments</span>, <span class="pwgScreen">Lock</span>,
+<span class="pwgScreen">Public/Private</span>, <span
+class="pwgScreen">Representative</span> available from <span
+class="pwgScreen">Administration, Categories, Properties</span>).</p>
+
+<h3>Sort order</h3>
+
+<p>Choose if the default sort order will be used.</p>
+
+<p>Indicate if this sort order will be applied to subcategories.</p>
+
+<p>Select specific sort by columns to use with this category.</p>
+<ul>
+<li><strong>Creation date</strong>: Picture creation date</li>
+<li><strong>Post date</strong>: Synchronization date</li>
+<li><strong>Average rate (*)</strong>: Average rate could be changed by the visitor</li>
+<li><strong>Most visited (*)</strong>: The current visit change the most visited order</li>
+<li><strong>File name</strong>: Given name in informations field</li>
+<li><strong>Id</strong>: Internal Id (recent categories have an higher id than previous ones.</li>
+
+</ul>
+<p><strong>(*)</strong>Take care and test it for your self since it can give unpredictable results.</p>
+
+
+<h3>Representant</h3>
+
+<p>The representant of the category is the thumbnail displayed to represent
+the category on main page (<span class="pwgScreen">category.php</span>) when
+a category contains only sub-categories (just as the root category).</p>
+
+<p>There are 4 ways to set the representative picture of a category :</p>
+
+<ul>
+
+  <li><span class="pwgScreen">Picture page</span>: in the action buttons bar,
+  one of them let you set the displayed picture as representative for the
+  displayed category. This button is available only for administrators.</li>
+
+  <li><span class="pwgScreen">Modify informations about a picture</span> in
+  administration. This screen can be reach from <span
+  class="pwgScreen">picture.php</span> or <span class="pwgScreen">Batch
+  management</span> in <em>unit mode</em>. See the help of this screen for
+  details.</li>
+
+  <li><span class="pwgScreen">Administration, Categories, Properties,
+  Representative</span>. See the help of this screen for details.</li>
+
+  <li><span class="pwgScreen">Edit a category</span> (this screen).</li>
+
+</ul>
+
+<p>The representation depends on configuration parameter
+<code>allow_random_representative</code> (see <span
+class="filename">include/config_default.inc.php</span>).</p>
+
+<p>In default mode (<code>allow_random_representative</code> set to false)
+each category containing at least one element is represented by a fixed
+element. Once set (at category creation), the representative changes only
+when an administrator ask for it. If the representant is not appropriate,
+you can ask to <strong>Find a new representant by random</strong>.</p>
+
+<p>If configuration parameter <code>allow_random_representative</code> is
+set to true, a category containing elements can have no fixed
+representant. Just use <strong>Delete representant</strong> button.</p>
+
+<p>If the category contains no element (but only sub-categories) it can be
+represented by any element thanks to screen <span class="pwgScreen">Modify
+informations about a picture</span>. The only option on the current screen
+is to <strong>Delete representant</strong> button, after using this button,
+no representant option to set anymore.</p>
+
+<h3>Link all category elements to a new category</h3>
+
+<ul>
+
+<li><strong>Virtual category name</strong>: New category name to be created, 
+all pictures of the current category will be linked to the new one.</li>
+
+<li><strong>Parent category</strong>: Where the new category will be, 
+leave empty to create it from home.</li>
+
+</ul>
+
+<h3>Link all category elements to some existing categories</h3>
+
+<ul>
+
+<li><strong>Categories</strong>: Choose the destination category.</li>
+
+</ul>
+
+<h3>Send an information email to group members</h3>
+
+<ul>
+
+<li><strong>Group</strong>: addressees group</li>
+
+<li><strong>Mail content</strong>: Free text to be sent to them.</li>
+
+</ul>

+<h2>Extend for templates configuration</h2>
+
+<h3>Goal</h3>
+<p>Define replacement conditions for each template from template-extension
+(template called "replacer").</p>
+
+<p>"original template" from ./template/yoga (or any other than yoga)
+ will be replaced by a "replacer" if the replacer is linked to this "original template"
+ (and optionally, when the requested URL contains an "optional URL keyword").</p>
+
+<p>"Optional URL keywords" are those you can find after the module name in URLs.</p>
+
+<p>Therefore "Optional URL keywords" can be an active "permalink" 
+(see permalinks in our documentation for further explanation).</p>
+
+<p>Read: `<a href="#warnings">Warning</a>` usage conditions.</p>
+
+<h3>What are template extensions?</h3>
+
+<p>This configuration tool is powerfull for beginners and advanced users.
+By FTP, in the template-extension folder, the Webmaster can duplicate a lot of
+ the distributed .tpl files ("original template") with a different name 
+ ("replacer").
+ 
+ "Original templates", current original supported templates are:</p>
+<ul>
+  <li><span class="filename">index.tpl</span></li>
+  <li><span class="filename">mainpage_categories.tpl</span> and/or <span class="filename">thumbnails.tpl</span></li>
+  <li><span class="filename">menubar.tpl</span></li>
+  <li><span class="filename">header.tpl</span> and/or <span class="filename">footer.tpl</span></li>
+  <li><span class="filename">picture_content.tpl</span> and/or <span class="filename">picture.tpl</span></li>
+  <!-- <li><span class="filename">slideshow.tpl</span></li> -->
+  <li><span class="filename">profile.tpl</span> and/or <span class="filename">profile_content.tpl</span></li>
+  <li><span class="filename">tags.tpl</span></li>
+  <li><span class="filename">upload.tpl</span></li>
+  <li><span class="filename">about.tpl</span></li>
+  <li><span class="filename">popuphelp.tpl</span></li>
+  <li><span class="filename">search.tpl</span> and/or <span class="filename">search_rules.tpl</span></li>
+  <li><span class="filename">nbm.tpl</span> and/or <span class="filename">notification.tpl</span></li>
+  <li><span class="filename">identification.tpl</span> and/or <span class="filename">register.tpl</span></li>
+  <li><span class="filename">redirect.tpl</span></li>
+</ul>
+
+<h3>Where can I find "original templates"?</h3>
+
+<p>Distributed original templates are in template/yoga/ 
+(don't edit them in place for upgrade perspectives). So with "original templates", 
+any webmaster can create his "replacers (customized templates)".</p>
+
+<h3>Where should I save "replacers"?</h3>
+
+<p><strong>Replacers (customized templates)</strong> must be placed in the 
+template-extension folder (or its subfolders).
+Replacers can have any filename with the .tpl extension. For example: <span
+class="filename">template-extension/my-extension/video.tpl</span>.</p>
+
+
+<h3>How can I activate my "replacers"?</h3>
+<p>An <strong>original template</strong> should be assigned to each
+ <strong>replacer (customized templates)</strong> to activate the related replacements.
+ This is the goal of "Extend for templates" in the Configuration Administration menu.</p>
+
+<p>If you select an <strong>optional URL keyword</strong> then replacements 
+will be operate only on pages with this keyword. For example: <span
+  class="pwgScreen">index.php?/<strong>most_visited</strong></span></p>
+  
+<p>Advanced users will use permalinks as <strong>optional URL keyword</strong>. </p>
+
+<p>If you select a <strong>Bound template</strong> then replacements will be operate only on this template.</p>
+
+<h3>How can I deactivate my "replacers"?</h3>
+<ul>
+<li>Unselect related "Original templates".</li>
+<li>By FTP delete of "replacers".</li>
+</ul>
+<a name="warnings"></a>
+<h3>Warnings</h3>
+<ul>
+
+  <li><strong>Original template</strong> must be the "original" template 
+  otherwise you could have unpredictable results!</li>
+
+  <li>On several <strong>replacers (customized templates)</strong> with the
+  same<strong>Original template</strong> and the same <strong>optional URL 
+  keyword</strong> only the last replacer is active.</li>
+
+  <li>Unselected <strong>optional URL keyword</strong> will active the replacer
+  on any template usage. As previous point, order can override previous
+  selected replacers.</li>
+
+  <li>Subfolders:
+Subfolders are ignored but they are usefull to change current order.<br />
+distributed-samples: for test purpose are distributed! 
+<strong>Don't edit them</strong> create your own ones.
+</li>
+
+  <li>On delete of a replacer the <strong>Original template</strong> is 
+  immediately reactivated.</li>
+
+</ul>

+<h2>Maintenance</h2>
+
+<p>To optimize page generation time, Piwigo uses cached
+information. For example, instead of counting the number of pictures
+contained in each category at each page reload, this information is stored
+in the database. In theory, this information should always be correct, but
+sometimes an error can occur and cached information becomes wrong.</p>
+
+<p>Some informations become useless with time. Deleting this useless
+information from database make you save disk space.</p>
+
+<ul>
+
+  <li><strong>Update categories informations:</strong> For each category,
+  informations to update or control are the following : list of parent
+  categories, number of pictures, date of the last picture, position among
+  brother categories, position among all categories. This action also checks
+  the coherence of representative picture.</li>
+
+  <li><strong>Update images informations:</strong> For each picture,
+  informations to update are : full path to file, average
+  rate. <em>Warning</em>: do not get confuse with metadata informations
+  which can be synchronized from <span class="pwgScreen">Administration,
+  Categories, Synchronize</span> or by reaching the modification screen of a
+  single picture (through <span class="pwgScreen">Picture</span> for
+  example).</li>
+
+  <li><strong>Repair and optimize database:</strong>
+  For each table, re-odrer, repair and optimize operations are done.
+  </li>
+</ul>
+
+<ul>
+  <li><strong>Purge history detail:</strong> Delete all lines from
+  <code>history</code> table. Screen <span class="pwgScreen">Administration,
+  Specials, History</span> shows no informations anymore on past
+  history. <em>Warning</em>: all data will be lost and there is no way to
+  get informations back.</li>
+
+  <li><strong>Purge history summary:</strong> Delete all the summary information about visit history. This summary is calculated from the history detail.</li>
+
+  <li><strong>Purge sessions:</strong> Delete expired user sessions.</li>
+
+  <li><strong>Purge never used notification feeds</strong></li>

+<h2>Permalinks</h2>
+
+<p>Permalinks are used to make category urls nicer. When a category has a permalink defined, the id of the category is not required anymore in the url.</p>
+
+<p>When a permalink is deleted, you have the ability to save it to the permalink history, so that external links to PWG pages still work. In the permalink history table you can see the date when the permalink has been deleted as well as the last time when it was used and the number of times this permalink has been used.</p>
+
+<p>Note that permalinks must be unique per category. Also in the permalink history you cannot have the same permalink defined more than once.</p>

+<h2>Remote sites</h2>
+
+<p>Piwigo offers the possibility to use several servers to store the
+images which will compose your gallery. It can be useful if your gallery is
+installed on one limited space and that you have a big quantity of images to
+be shown.</p>
+
+<ol>
+
+  <li>edit file <span class="filename">tools/create_listing_file.php</span>,
+  by modifying parameters section such as
+  <code>$conf['prefix_thumbnail']</code> or
+  <code>$conf['use_exif']</code>.</li>
+
+  <li>place file <span class="filename">tools/create_listing_file.php</span>
+  modified on your distant website, in the same directory than your category
+  directories (as the directory <span class="filename">galleries</span> of
+  this website) by ftp. For the example, let's say that you can access <span
+  class="filename">http://example.com/galleries/create_listing_file.php</span>.</li>
+
+  <li>go to <span class="pwgScreen">administration panel, Categories, Site
+  manager</span>. Ask to create a new site, for example <span
+  class="filename">http://example.com/galleries</span>.</li>
+
+  <li>a new remote site is registered. You can perform 4 actions :
+
+    <ol>
+
+      <li><strong>generate listing</strong> : launches a distant request to
+      generate a distant file listing</li>
+
+      <li><strong>synchronize</strong> : reads the distant <span
+      class="filename">listing.xml</span> file and synchronizes with
+      database informations.</li>
+
+      <li><strong>clean</strong> : removes distant <span
+      class="filename">listing.xml</span> file.</li>
+
+      <li><strong>delete</strong> : deletes the site (and all related
+      categories and elements) in the database.</li>
+
+    </ol>
+  </li>
+</ol>
+
+<!-- <p>You can do all this by hand by generating yourself the <span
+class="filename">listing.xml</span> file, moving it from your distant server
+to you local Piwigo root directory and opening the remote site
+management screen : Piwigo will propose you to use the found
+listing.xml file.</p>-->

+<h2>Synchronize</h2>
+
+<p>There are 2 synchronizations possible : directories/files and file
+metadata. directories/files is about synchronizing your directories tree
+with the category tree in the database. metadata is about updating elements
+informations such as filesize, dimensions in pixels, EXIF or IPTC
+informations.</p>
+
+<p>The first synchronization must be the directories/files one.</p>
+
+<p>Synchronization process may take long (depending on your server load and
+quantity of elements to manage) so it is possible to progress by step:
+category by category.</p>
