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>
