If you are a WP dev,. surely you will get into situations like you need to get the href link of featured image of WP page / posts Here the code snippet you can use handy
example
<?php the_post_thumbnail('front', array( 'class' => 'alignleft' )); ?>Results in something like (depending on which post)
<img width="120" height="80" src="[http://images.mathrubhumi.com/images/2013/Nov/08/03089_536886.jpg](http://images.mathrubhumi.com/images/2013/Nov/08/03089_536886.jpg)" alt="IMG_7506" title="IMG_7506" />So how do you return just the url for use in a link? The code below will return the image in a link (using the lightbox plugin). the bold part is the PHP function for returning the image url itself.
<a rel="lightbox" href=" **<?php $image_id = get_post_thumbnail_id(); $image_url = wp_get_attachment_image_src($image_id,’large’, true); echo $image_url[0]; ?>**“> ‘alignleft’ )); ?>
