<li>This plugin can be used to display a different theme for each one of your blog posts.</li>
<li>The interface used to configure this is very user-friendly. Even friendlier since v1.3.</li>
<li>Many thanks to Stephen Carroll whose domain page’s script motivated me to write this plugin.</li>
<li>Thanks also go to emposha.com for their image selection script, which I shamelessly hacked and surely made worse.</li>

<h3>Limitations</h3>
<ul>
<li>Due to WordPress selecting themes and stylesheets very early on when building a page, I cannot use WordPress’ “official” way to detect the current page/post. Therefore, you may find that this plugin does not work correcly if your setup is extremely exotic. Contact me if this happens.</li>

Page Theme

Specify the theme (not template, that is already taken care of by Wordpress) you wish to use with each given page or blog post.
