How to Rotate the Header Image in WordPress

1. Install the Rotating Header plugin in your WordPress theme. The Rotating Header plugin is a simple plugin that allows you to enter a set of image files to use in your header and to rotate among them.
2. Download the WP Random Header plugin to your WordPress blog. The WP Random Header plugin chooses image files from the wp-content/header-images folder to use as your header. Because the plugin chooses any file in the folder, be sure you include only image files.

3. Use the Dynamic Headers plugin. The Dynamic Headers plugin allows you to choose different headers for your posts from image files or flash files, as well as rotating through random file headers on each post.
