Remove default header images and load custom header images from 'The Headers' page. Allows for easy selection of random header images in your theme.

## Description

A plugin that should be able to remove default headers for a theme and add custom headers based upon the article written by <a href="http://juliobiason.net/2011/10/25/twentyeleven-with-easy-rotating-header-images/">Julio Biason</a> who was inspired by <a href="http://wpti.ps/?p=107">wpti.ps</a>.

Create a Page named **The Headers**. Then upload header images (media files) to the the page. The page may have a visibility of private. All images displayed on the page will be parsed, those attached to the page and those added via image blocks.

Once the custom header images are loaded, just go to `Appearance > Header` or `Customize > Header Image` and select `Randomize suggested headers`.

The plugin will display an error notice if there is **not** a page titled, **The Headers**.

## Installation

1. Create a new page. It can be private. It must be titled `The Headers`. Add any images that you want to use as custom header images to this page. Header images should be cropped appropriately for the base theme.
2. Upload `add-custom-header-images` directory to the `/wp-content/plugins/` directory
3. Activate the plugin through the 'Plugins' menu in WordPress
4. Go to `Appearance > Header` or `Customize > Header Image` and select `Randomize` from the Default Images section.
