<h1>WP CPT Images</h1>
<h3>Add images to custom post types.</h3>
<p>To use, select an image for the custom post type and attach. You can then use the image in various ways:</p>
<p><b>As a shortcode</b>. Put [cptImage] wherever you want the image to appear. Not that in this usage (without a parameter) it will only appear when you are on a single item of that custom post type OR in the archive page itself. To call any attached image, use [cptImage cpt="Custom Post Type Name"].</p>
<p><b>In PHP in your template</b>. To retrieve the image url to a variable, use <code>get_cptimage_image($optionalname, $echo)</code> (you can use <code>get_cptimage_image("Custom Post Type Name")</code> to retrieve a specific post type image, or <code>get_cptimage_image("Custom Post Type Name", true)</code> to echo the url rather than retrieving it. To merely display the image, call <code>cptimage_image("Custom Post type Name")</code> or simply <code>cptimage_image()</code>. Not that if you do not pass a post type name it will only appear when you are on a single item of that custom post type OR in the archive page itself. </p>
