To call a different size, simply change the text
inside the thumbnail function.

For example, to call the 300 x 100 sized image,
we would use the function:
<?php the_post_thumbnail( 'bones-thumb-300' ); ?>
for the 600 x 150 image:
<?php the_post_thumbnail( 'bones-thumb-600' ); ?>

You can change the names and dimensions to whatever
you like. Enjoy!

	to add more sidebars or widgetized areas, just copy

	register_sidebar(array(

	To call the sidebar in your template, you can just copy

	sidebar-sidebar2.php
