Let’s add banner images to articles and direct users to your site or product.（Call To Action） 
Since you can change banner images for each category, you can also guide users to sites that are more interested in users depending on the contents of the articles. 
There is no need to embed same images in articles many times from the posting screen!
<h4>About functions</h4>
When you activate the plug-in, “Add banner” menu is added to the left main menu of the administration screen. Please register and edit from there.
Press the “Choose Image” button at Edit banner page, to open the Media Uploader. 
Please select an existing image or upload an image. 
The image URL can also be written as a relative path.
In the “How display”, you can choose whether to display it under the body of the posted article or display it with a shortcode.
When displaying with shortcode, overwriting the short code number takes precedence. However, “id” is not displayed unless it is registered in the administration screen.
If you check “Filter by category”, banner will be displayed on category page of registered category. Multiple images can be displayed in the same category. If you do not check it, the banner is displayed unconditionally on all pages.
You can set class and ID in the image. Please use it for measurement with tag manager and adjustment of style sheet.
When the banner is displayed, the banner image is surrounded by the following tags. 
You can use it by adjusting the style sheet.
<pre><code><div class="add-banner-extension-wrapper">
 <img src="sample.jpg" alt="sample">
</div>
</code></pre>
<h4>Attention</h4>
<ul>
<li>Depending on the theme and plugin you are using, the display position of the banner image may change or more than one banner may be displayed. The theme of “Twenty Seventeen” is confirmed to work.</li>
<li>When “Filter by category” is checked, the corresponding post type is post only (post article page and category page). Supported Post Types are ‘Post’ only. Currently, ‘Page’ and ‘Custom Post Types’ are not supported. Also, it does not support ‘Tags’ or ‘Custom Taxonomies’.</li>
</ul>

<h4>Major overhaul</h4>
As of version 2.0 CNP allows you to easily embed posts from other websites in the same WordPress network with a shortcode builder that is available above your editor.
The manual way of entering the shortcode is still available, but you can chooses whichever you prefer.
Also included from version 2.0 is an options page where you set certain security measures: 1. You can restrict embedding of content to only the original author of the post (does not apply to administrators) 1. You can disallow other websites in the WordPress network to embed posts from your website
<h4>Usage</h4>
This plugin is useful if you have a wordpress network (multisite) and you want to display (embed) a post or a category of posts that is on another website in the same network.
Use the shortcode builder above the editor or type the shortcode in manually:
<pre><code>[cnp blogid=1 postid=1] </code></pre>
<h4>Attributes</h4>
Mandatory
blogid is the ID of the blog you wish to pull the post from (go to Network->Sites and hover over the site to view the ID).
Instead of postid= you can also use catid= to display all posts from a category.
Optional
header=1 -> header number (i.e. h1 ), no title if you set it to 0 (default is 2)
excerpt=true -> if you only want to display excerpts with read more links to the post on the other website
numberofposts=5 -> for displaying a certain number of posts from a category (default is 5)
titlelink=false -> if you don’t want the title to have a permalink (default is true)
Working with other plugins
If you want to display a plugin through a shortcode that is in one of the posts that you are displaying, make sure that the plugin is also active on the network site where you use CNP.
Note: not all plugins will work. Post about it if you find some that do and also that don’t.
