Help! I can’t add PicLens widget to sidebar

I’m using WordPress 2.2.3, but my theme (DarkNight 2.0 Theme 2.0 by David Chait) doesn’t support widgets. I’m a literal naif when it comes to code and simply need to add the PicLens widget. Does anyone happen to know what I could paste in the sidebar code below to widgetize my theme? I’d be much obliged!

`<!– begin sidebar –>
<div id=”menu”>

<?php wp_list_pages(); ?>
<?php get_links_list(); ?>
<li id=”categories”><?php _e(‘Categories:’); ?>

<?php wp_list_cats(); ?>

<li id=”search”>
<label for=”s”><?php _e(‘Search:’); ?></label>
<form id=”searchform” method=”get” action=”<?php echo $_SERVER[‘PHP_SELF’]; ?>”>
<div>
<input type=”text” name=”s” id=”s” size=”15″ />
<input type=”submit” value=”<?php _e(‘Search’); ?>” />
</div>
</form>

<li id=”archives”><?php _e(‘Archives:’); ?>

<?php wp_get_archives(‘type=monthly’); ?>

<li id=”meta”><?php _e(‘Meta:’); ?>

<?php wp_register(); ?>
• <?php wp_loginout(); ?>
• ” title=”<?php _e(‘Syndicate this site using RSS’); ?>”><?php _e(‘RSS’); ?>
• ” title=”<?php _e(‘The latest comments to all posts in RSS’); ?>”><?php _e(‘Comments RSS’); ?>
• “><?php _e(‘Valid XHTML’); ?>
• XFN
• “>WP

<?php wp_meta(); ?>

</div>
