<p>Header Watermark provides you with extra flexibility and control over the header image(s) for your WordPress site:</p>
<ul>
<li>Use any image from your Media Library as a watermark for your header image(s)</li>
<li>Control the placement and opacity of the watermark</li>
<li>Select any suitable image from your Media Library as your header image(s)</li>
<li>Control which images are used for random header images</li>
</ul>
<h3>Requirements</h3>
<p>Header Watermark requires the following to work:</p>
<ul>
<li>GD Library PHP extension – version 2.0.28 or higher</li>
<li>The WordPress theme must use the <em>get_header_image()</em> function to generate the header image and must also define the HEADER_IMAGE_WIDTH and HEADER_IMAGE_HEIGHT constants</li>
</ul>
<h3>Themes</h3>
<p>This plugin works with the Twenty Ten theme with no further configuration.</p>
<p>If you use this plugin with the Twenty Eleven theme, you may see a notice at the top of your website/WordPress admin pages like this:</p>
<blockquote>
<p>Notice: Constant HEADER_IMAGE already defined in /var/www/yoursite/wordpress/wp-content/themes/twentyeleven/functions.php on line 118</p>
</blockquote>
<p>You may also find that you get occasional errors on some WordPress admin pages, for example if you activate a different theme.</p>
<p>To prevent the notice and errors, find and change the following line in the <em>functions.php</em> file of the Twenty Eleven theme:</p>
<p>Change this:<br />
    define( ‘HEADER_IMAGE’, ” );<br />
to this:<br />
    if ( ! defined( ‘HEADER_IMAGE’ ) ) {<br />
      define( ‘HEADER_IMAGE’, ” );<br />
    }</p>
<p>Any other themes that define the HEADER_IMAGE constant may have the same problems and need to be altered in the same way for the plugin to work.</p>
