I don’t see the plugin installed… Here are the instructions…
1. Download “content-gallery.zip” to your local machine.
2. Extract and upload the “content-gallery” folder to your “/wp-content/plugins/” directory. (DO NOT CHANGE ANY FILE OR FOLDER NAMES)
3. Activate the plugin through the “Plugins” menu in WordPress.
4. Add the following code anywhere within your theme files where you want the content gallery to be displayed.
<?php include (ABSPATH . ‘/wp-content/plugins/content-gallery/gallery.php’); ?>
