/************* THUMBNAIL SIZE OPTIONS *************/

// Thumbnail sizes
add_image_size( 'bones-thumb-600', 600, 150, true );
add_image_size( 'bones-thumb-300', 300, 100, true );
/*
to add more sizes, simply copy a line from above
and change the dimensions & name. As long as you
upload a "featured image" as large as the biggest
set width or height, all the other sizes will be
auto-cropped.

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

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

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

/************* ACTIVE SIDEBARS ********************/

// Sidebars & Widgetizes Areas
function bones_register_sidebars() {
	register_sidebar(array(
		'id' => 'sidebar1',
		'name' => __( 'Sidebar 1', 'bonestheme' ),
		'description' => __( 'The first (primary) sidebar.', 'bonestheme' ),
		'before_widget' => '<div id="%1$s" class="widget %2$s">',
		'after_widget' => '</div>',
		'before_title' => '<h4 class="widgettitle">',
		'after_title' => '</h4>',
	));

	/*
	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
	sidebar's id is, for example:

	register_sidebar(array(
		'id' => 'sidebar2',
		'name' => __( 'Sidebar 2', 'bonestheme' ),
		'description' => __( 'The second (secondary) sidebar.', 'bonestheme' ),
		'before_widget' => '<div id="%1$s" class="widget %2$s">',
		'after_widget' => '</div>',
		'before_title' => '<h4 class="widgettitle">',
		'after_title' => '</h4>',
	));

	To call the sidebar in your template, you can just copy
	the sidebar.php file and rename it to your sidebar's name.
	So using the above example, it would be:
	sidebar-sidebar2.php
