   Here is a solution to the problem of how to get a tag cloud listed in your sidebar to act as navigation.

   So you want a tag cloud to appear in the side bar, and when you click on a tag the corresponding pictures to appear in the main page area?

   here is how I did it (amended from zyrq updated for wordpress 3.0 and nextgen 1.5.5 - it may work with earlier versions of both):

   1. create a page called 'gallery' and add this code (use the html not the visual editor) '[tagcloud]'

   2. download this plugin "Samsarin PHP Widget" and install it.

   3. paste this code into the new "Samsarian PHP 1" widget created:

   <ul class="galtags">
   <?php
   
   global $wpdb;
   $results = $wpdb->get_results('SELECT * FROM wp_terms INNER JOIN wp_term_taxonomy ON wp_terms.term_id = wp_term_taxonomy.term_taxonomy_id WHERE taxonomy = "ngg_tag"');
   foreach ($results as $row) {
   echo "<li><a href=http://www.example.com/gallery/?gallerytag=";
   echo $row->slug;
   echo ">";
   echo $row->name;
   echo "</a> </li> ";
   }
   
   ?>
   </ul>

   4. change http://www.example.com to the name of your website URL.

   5. Thats it.

   For some reason every other attempt on the web to solve this problem does not work so after I got it working I thought I'd share this to help others who may have got stuck

   If anyone happens to know how to change the tag list order in the sidebar I'd be interested to know.

   I think I'd prefer it to be in alphabetical order, or at least have some options. At the moment its output in the order they went into the database.

   mtingle,

   this is how I managed to sort the tags in alphabetical order by tag name.

   <ul class="galtags">
   <?php
   
   global $wpdb;
   $results = $wpdb->get_results('SELECT name,slug FROM wp_terms INNER JOIN wp_term_taxonomy ON wp_terms.term_id = wp_term_taxonomy.term_taxonomy_id WHERE taxonomy = "ngg_tag" ORDER BY name ASC');
   foreach ($results as $row) {
   echo "<a href=../wp-content/nggallery/tags/?gallerytag=";
   echo $row->slug;
   echo ">";
   echo $row->name;
   echo "</a> ";
   }
   ?>
   </ul>

   The two unsolved issues that remain for me is to get a "real" tag cloud with tag sizes according to the number of pictures with a particular tag. Now all tags are the same font size.

   I also want to have separate tag clouds for different kinds of pictures; my own, picture restaurations and misc pictures.
   I use the plugin "NGG Custom Fields" that enables custom fields for galleries/pictures. But how do I use that to separate the tag clouds?

   Hi

   the shortcode [tagcloud] seems to work well on my page categories but the the database the widget is looking up seems mixed/confused.

   How can I get the widget to look at the ngg tag database that the [tagcloud] is?

   I'm a newbie to all this :)
