<p>For posts and pages with no featured image, and no images associated with the entry, a random image is selected from the media library and set as the featured image.</p>
<p>The plugin currently does not test for images associated with the entry.</p>
<p>Instead, install and run the Easy Add Thumbnail plugin (https://wordpress.org/plugins/easy-add-thumbnail/).</p>
<p>That plugin will set the featured image on all entries that both have no featured image AND have an image associated with the post.</p>
<p>What is left is entries without featured images and without any images.</p>
<p>This plugin provides a random image from the sites media library so that index pages look more interesting (and possibly confusing/humorous depending on which image is randomly selected.)</p>
<p>There is a notice at the bottom of each post the plugin has updated noting the random image. In a future release, this note will be optional via the standard user interface, but for now one has to edit the plugin and remove the last “filter” line. This notice is not displayed if the plugin is removed.</p>

<p>The <strong>Image Refresh</strong> plugin allows you to randomly display a different image on every page load.</p>
<h4>Why?</h4>
<p>Many people like to vary up the images on their site just to keep things fresh.  Loading a new image every time someone visits your homepage is something that should be simple, right? Alas, people resort to using plugins that are not meant for this purpose and end up sacrificing performance for the sake of a fresh look. Well, my friend, the search has ended. This plugin does nothing more, and nothing less than load that fresh image where you need it.  To top it all off, we do it in a way that won’t slow your site down.</p>
<h4>How?</h4>
<p>Using this plugin is simple:</p>
<ol>
<li>Install the plugin</li>
<li>Activate the plugin</li>
<li>On the page or post where you want to have an image refresh, just click on the ‘Add Media’ button, upload as many images as you like, click ‘Save Changes’ and exit the media uploader.</li>
<li>Add the <code>[mpress_image_refresh]</code> shortcode where you want your image to appear.</li>
<li>Save your changes.</li>
</ol>
<h4>Features</h4>
<ul>
<li>Works with custom post types</li>
<li>No settings page, just an easy way for you to add fresh images to your site</li>
<li>Clean, well written code that won’t bog down your site</li>
</ul>
