This WordPress plugin causes post thumbnails to be shown next to each post or page entry under the wp-admin Posts or Pages listings. If no post thumbnail is set, then the plugin uses the first located image (if exists) within the post to display.
The only reason I created this quickfire plugin is because I simply can’t believe that such a basic, UI-enhancement has yet to be included in the core WordPress release! You can grab it via the standard WordPress plugins repository, or via the direct download below.
Download the plugin:
To use, simply upload and install the .zip file through the standard Plugins Upload interface. Alternatively, extract the zip file and upload the contents into the wp-content/plugins/ directory of your WordPress installation. Note that there is no setting screen for this plugin.
