WordPress Related Post Error
===

I did a search not only on Google but other places, including here and cannot find anything to help with this issue.

Here is the problem. I have a related posts snippet based on tags instead of categories, that I use in WordPress themes and I have been using it for quite some time and it works really well. Here is is:

    		$tags = wp_get_post_tags($post->ID);
		$tagIDs = array();
		if ($tags) {
			$tagcount = count($tags);
			for ($i = 0; $i < $tagcount; $i++) {
				$tagIDs[$i] = $tags[$i]->term_id;
			}
		$args=array(
		'tag__in' => $tagIDs,
		'post__not_in' => array($post->ID),
		'showposts'=>mytheme_option( 'related_count' ),
		'ignore_sticky_posts'=>1
		);
		$my_query = new WP_Query($args);
		if( $my_query->have_posts() ) {
			echo '<h4>'. __('Other Posts You May Be Interested In', "themename"). ':</h4><ul>';
			while ($my_query->have_posts()) : $my_query->the_post(); ?>
    
				<li class="imglink">
            
					<!-- post loop stuff goes here -->
                 		 
            	</li>
            
	<?php endwhile;
	echo '</ul>';
	}
	else {
	echo '<h4>'. __('Other Posts You May Be Interested In', "themename"). ':</h4>
	'. __('<p>There are no related posts at this time.</p>', "themename"). '';
	}	
	}
	$post = $original_post;
	wp_reset_query();

Like I said it works really well. If posts have the same tag, then this shows:

> Other Posts you May Be Interested In:
> posts with the same tag get displayed

BUT here is the problem: If a single post is given a tag and no other posts have that same tag, this is what shows:

> Other posts you may be interested in: There are no related posts at
> this time.

Now if a post is not assigned a tag, absolutely nothing shows. The div where related posts are supposed to display is empty but it should say there are no related posts.

I have looked for a solution and tried many different things to get this corrected but I can't seem to get my head around it. Can someone assist me in getting:

> Other posts you may be interested in: There are no related posts at
> this time.

to display if a post has no tag. Any help is greatly appreciated and thank you very much in advance.
