Multisite Featured Image changes the box of the featured image so that you can use the classic Media Uploader also with Network Shared Media.

== Description ==

Multisite Featured Image changes the box of the featured image for all sites under a multisite except the main site which you can choose from the Settings Page "MU Featured Image".

This plugin changes the box in the way that the default pop-up is replaced with the classic Media Uploader where you can choose images. *Images From URL do not work*.

For a greater Multisite experience you can combine this plugin with the [Network Shared Media plugin](https://wordpress.org/plugins/network-shared-media/) and have a complete Media Sharing site.

= Roadmap =

1. Save the selected image additional sizes and generate the defined size in the_post_thumbnail function
2. Enable Images from URL
3. Change thickbox to the new Media Uploader modal

== Installation ==

This section describes how to install the plugin and get it working.

1. Upload the folder 'mu-featured-image' to the plugins folder
2. Activate the plugin through the 'Plugins' menu in WordPress
3. Go to the Network dashboard and look at Settings > MU Featured Image to change the settings if needed
 
== Frequently Asked Questions ==

= Do I have to use a custom function to enable post thumbnails? =

No, this plugin is hooked on the core function the_post_thumbnail().

= Can I set the image from URL? =

No, this is yet to be developed and it is on our Roadmap which you can see under the tab Description.

= Can I use custom image sizes or choose between the default sizes? =

This plugin is using the thickbox and you can choose between registered and default sizes on the screen where you choose your image. To enable a custom image size to be added on the size selection you will need to use the filter [image_size_names_choose](https://codex.wordpress.org/Plugin_API/Filter_Reference/image_size_names_choose).

= Featured Image is always showing the same selected image. Why the featured image is not shown in the defined size in the_post_thumbnail? =

The drawback of this plugin is that the featured image on other multisites will not generate an image but will use the selected one with its size. Therefore, using a custom size in the function *the_post_thumbnail('custom-size')* will not be called and instead it will be used the chosen image. Only the main site will still use the default output of **the_post_thumbnail** thereby generating the defined size.

This will be developed later.
