Examples

#1 Demonstration of what the function outputs

echo get_posts_nav_link();

Displays:

<a href="link">Previous page</a> - <a href="link">Next page"</a>

#2 Place the links in the middle and pass the parameters

To do this, wrap them in a DIV and give it the text-align:center property:

$links_html = get_posts_nav_link( array(
	'sep' => ' . ',
	'prelabel' => 'Previous page',
	'nxtlabel' => 'Next page'
) );

echo "<div style='text-align:center;'>$links_html</div>";

#3 Instead of texts: "Previous page", "Next page", you can use images

$links_html = get_posts_nav_link( array(
	'sep' => ' . ',
	'prelabel' => '<img src="' . get_stylesheet_directory_uri() . '/images/prev.jpg" />',
	'nxtlabel' => '<img src="' . get_stylesheet_directory_uri() . '/images/next.jpg" />'
) );
