we would use the function:
<?php the_post_thumbnail( 'template-image-300' ); ?>
for the 600 x 150 image:
<?php the_post_thumbnail( 'template-image-600' ); ?>

	to add more sidebars or widgetized areas, just copy
	and edit the above sidebar code. In order to call
	your new sidebar just use the following code:

	Just change the name to whatever your new

	register_sidebar(array(

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

	So using the above example, it would be:
	sidebar-sidebar2.php
