-  <li>To link an element to a category, you just have to make the
-  association on the page of element edition (link to this screen on
-  picture.php logged as an administrator) or on the informations of all
-  elements of a category.</li>
-
-  <li>Using this principle, it is possible to create virtual categories : no
-  directory coresponds to this category. You can create virtual categories
-  in <span class="pwgScreen">Administration, Categories, Manage</span>.</li>
