<p>A plugin for allowing users to set a custom header on a per-post basis. This plugin hooks into the WordPress <code>custom-header</code> theme feature and overwrites the values on single post views if the post has been given a custom header.</p>
<h3>Features</h3>
<p>This plugin creates a custom meta box on the edit post screen. From that point, you can select a custom header image.  You can also select whether to display your header text and its color if your theme supports that option.  The options you choose will be shown on the single post page on the front end.</p>
<h3>Requirements</h3>
<p>Your theme must support the core WordPress implementation of the <a href="https://codex.wordpress.org/Custom_Headers" rel="nofollow ugc">Custom Headers</a> theme feature.</p>
