When you visit edit.php, you will see the list of posts. WordPress 3.0 has a nice feature called featured image, but not shown on edit.php. This plugin diplays featured images in the list of posts.

As of version 0.2.2 you can select which post types you’d like to have the image column. 
It simply adds a column before the title (far left) the show’s the posts featured image if it’s supported and exists.
Want to change the default image? Simply filter you own image by using <code>featured_image_column_default_image</code> 
or filter your own CSS by using the <code>featured_image_column_css</code> filter hook.
<h4>Example actions/filters</h4>
Add support for a custom default image
<pre><code>function my_custom_featured_image_column_image( $image ) {
 if ( !has_post_thumbnail() ) {
 return trailingslashit( get_stylesheet_directory_uri() ) . 'images/featured-image.png';
 }

 return $image;
}
add_filter( 'featured_image_column_default_image', 'my_custom_featured_image_column_image' );
</code></pre>
Remove support for post types Use the <code>featured_image_column_init</code> action hook for your filter.
<pre><code>function frosty_featured_image_column_init_func() {
 add_filter( 'featured_image_column_post_types', 'frosty_featured_image_column_remove_post_types', 11 ); // Remove
}
add_action( 'featured_image_column_init', 'frosty_featured_image_column_init_func' );

function frosty_featured_image_column_remove_post_types( $post_types ) {
 foreach( $post_types as $key => $post_type ) {
 if ( 'post-type' === $post_type ) // Post type you'd like removed. Ex: 'post' or 'page'
 unset( $post_types[$key] );
 }
 return $post_types;
}
</code></pre>
