======Shortcode Examples======
The following code shows how shortcodes can be implemented.
<code>
<?php

function random_picture($atts) {
	extract(shortcode_atts(array(
		'width' => 400,
		'height' => 200,
		'category' => 'technics',
		'mono' => 'no',
	), $atts));
	$mono = strtolower($mono);
	$returnvalue = '<img src="http://lorempixel.com/';
	if($mono=='yes'){
		$returnvalue .= 'g/';
	}
	$returnvalue .= $width . '/'. $height . '/'.$category.'" >';
	return $returnvalue;
}

add_shortcode('picture', 'random_picture');

function lorem_function($atts) {
	extract(shortcode_atts(array(
		'open' => '<p>',
		'close' => '</p>',
	), $atts));
  return $open.'Lorem ipsum dolor sit amet, consectetur adipiscing elit.
