How to get featured image thumbnail instead of cropping automatically? - php

Question

I'm working on a gallery for the homepage of this site: Warm Glow Photo
I have called the featured image at a specific size (800x600) that I have defined in functions.php. This seems to be calling
...IMAGE.jpg?resize=800%2C600
instead of the version of the featured image called
...IMAGE-800x600.jpg
I am using a plug-in for cropping thumbnails which means I need to call this image rather than cropping with ?resize.
I've found lots of info about how to call different size thumbnails but nothing that explains why it crops with ?resize instead of calling the different thumbnail itself. Any ideas on how to do this would be much appreciated.
The relevant code is:
<?php
if ( has_post_thumbnail() ) {
$large_image_url = wp_get_attachment_image_src( get_post_thumbnail_id(), 'full' );
echo '<li><a href="' . $large_image_url[0] . '" title="' . the_title_attribute( 'echo=0' ) . '">';
the_post_thumbnail( 'bones-thumb-800' );
echo '</a></li>';
}
?>
and defining bones-thumb-800 in functions.php
add_image_size( 'bones-thumb-800', 800, 600, true );

To get the plain URL of a post use this function :
function um_get_post_featured_image_src($post_id = null,$size = "full"){
if(!$post_id){
global $post;
$post_id = $post->ID;
}
if(has_post_thumbnail($post_id)){
$image = wp_get_attachment_image_src( get_post_thumbnail_id( $post_id ), $size );
return $image[0];
}else{
return "";
}
}
If you have a $post globally than you don't need to pass post ID.
