So friends I am trying to use prettyPhoto in my wordpress theme but its not working at all. Both of its files - prettyPhoto.css and jquery.prettyPhoto.js are correctly linked in header.php file.

This is the linking of the files in my header.php file -

<link rel="stylesheet" href="<?php bloginfo('stylesheet_directory'); ?>/js/prettyPhoto/css/prettyPhoto.css" type="text/css" media="screen" title="prettyPhoto main stylesheet" charset="utf-8" />
<script src="<?php bloginfo('stylesheet_directory'); ?>/js/prettyPhoto/js/jquery.prettyPhoto.js" type="text/javascript"></script>

Please let me know if this problem is due to not using wp_enqueue_script().

And this is how I link the image to be used with prettyPhoto -

<a title="test image" href="images/new-image.png" rel="prettyPhoto[]"><img src="images/new-image.png" alt="Some Alternate Text" /></a>

When I click on image, it doesn't open in prettyPhoto.
