This simple plugin changes the default behaviour of the “Add Link” modal window, which typically only shows published content, by expanding it to include posts with any post status, allowing you to link to scheduled content, draft content, private content and posts with custom post statuses, like Pitches created by a plugin like <a href="https://wordpress.org/plugins/edit-flow/" rel="ugc">Edit Flow</a>.
Just because this allows you to link to the content, this does not mean that the content is necessarily published, nor will it publish unpublished content. Use only when you know the status of each post that you’re linking to, to avoid broken links.

Adds a function to the function.php file of your current active theme. This function will make the featured image link back to the blog the image was inserted. 
This way you do not have to change your themes files and your changes will not be gone after a theme update.
Make sure your theme doesn’t allready have this function. Some themes allready have this function by default.
