 ![Wordpress Logo by kremalicious](/media/wordpress-logo.png)WordPress 2.9 added a new feature which allows you to assign an image to an article to make it the post image like it's often used in magazine style themes. This new feature along with a new template tag makes all the custom field hacks usually used for this functionality in the past obsolete. So here's a quick walkthrough to make use of the new post thumbnail feature and of course how to make it backwards compatible.

 Windows 8 and Internet Explorer 10 make it possible to pin your site to the Metro start screen as a new tile. The tile then is a bookmark to your site and you can control the icon and background color being used.

   * create a 144x144px image with your logo/icon filling the whole canvas and a transparent background
   * add two `meta` tags in the `head` of your site defining the image path and optionally the tile color
   * as noted in the [issue post](https://github.com/h5bp/html5-boilerplate/issues/1136), the image must be saved as a transparent 32bit PNG ("24bit" in Photoshop's Save For Web dialogue) without running it through image optimisers like [ImageOptim](http://imageoptim.com)

 While the size is the same as for the iPad 3 homescreen icon, I strongly suggest not using the apple-touch-icon for this. In fact, it might be best not using a full color image at all. Using a white monochrome version of your logo or icon will make your site's tile blend in perfectly with the default Metro UI system tiles.
 
 As an example, I just [pushed](https://github.com/kremalicious/kremalicious2/commit/4c7e215f4abecde4385028767b633be1278f277e) the Metro [tile image](/metro-tile.png) for kremalicious.com with those `meta` tags:
