WordPress 3.0 will be bundling support for custom headers in themes. If a theme supports it, a custom image can be used for a page header. Users have to choose which header image will be used.

This plugin removes that last part. Now, instead of having to choose which header image to use, the header image is chosen at random based on the available options. Refresh the page to see the magic work.

Note: This will only do anything useful in WordPress 3.0

It also only works with the Twenty Ten theme right now, though other themes will hopefully soon support custom headers.
